Introduction
Indonesia is a country where the population continues to rise every year. The rise in population occurred in Indonesia's major cities, one of which was Surabaya. The improvement in Surabaya continues as time passes. Surabaya's population has grown by 1,590,544 people in the last five years. The following graph shows Surabaya's population growth over the last five years, from 2016 to 2020.  (2021) Surabaya's population continues to grow, resulting in an increase in new businesses. The culinary business is one of the most common types of business. The culinary business has grown in popularity since it is a growing industry to work in. Food is a basic human requirement, so it will always be sought after and purchased.  (2019) The number of restaurants and restaurants in Surabaya is constantly increasing, as shown in Table 1.2. The rise in the food industry has resulted in an increased number of culinary businesses, one of which is the Hub22 Lounge & Bistro restaurant. Many businesses have closed due to increasing competition and a lack of returning consumers. Due to the high level of competition, restaurant owners must be able to develop positive relationships with customers for their restaurant to be visited again.
One approach for marketing is to use the internet to help their business. This may be performed so that business owners can reach attract more and more customers through online marketing. Marketing is one of the most crucial aspects of a company's success, and because it has evolved towards a more modern approach, it has been known as digital marketing (Pranoto, Jasmani and Marayasa, 2019). Giving promotions can also be one of the most significant things to do at this time because it allows you to communicate with customers and potentially generates the customer's intention to repurchase the product. Companies can develop successful long-term and short-term interaction relationships between companies and customers in introducing, marketing, and selling a product (Aulia,2020).
Customers that receive excellent service are more likely to return. According to Saselah et al. (2019), excellent and consistent service quality will show customers that the service given is the best. So customer satisfaction will increase, which will result in customers returning to utilize services on a regular basis, at last becoming loyal and returning again.

Research Method
This study uses quantitative research methods to obtain the results of the study. This study obtained data in the form of numbers obtained through respondents. The population in this study were the consumers of Hub22 Lounge & Bistro Surabaya who made transactions in the last six months. According to Hair et al. (2014), the ideal number of samples used in this study has a minimum of five to a maximum of ten times the number of indicators in the study. Researchers used a maximum value of 10 to determine the sample in this study, and because this study had 14 indicators, the sample to be obtained was 14 x 10. In this research, the researcher used a purposive sampling technique because the criteria that must be met by the respondent is that the respondent has made a minimum transaction of two times at Hub22 Lounge & Bistro Surabaya and is aged between 18-45 years.

Respondent Description
The subject of this study were customers from Hub22 Lounge & Bistro Surabaya who made transactions at least twice in the last six months.  (2022) As seen in Table 4.1, there are a total of 140 respondents, of which 64 are male and 104 are female. In terms of age, at the age range of 18 years to 24 years, there is 65.7%, at the age range of 25 years to 31 years, there is 11.4%, at the age range of 32 years to 38 years, there is 7.9%, at the age range of 39 years to 45 years, there is 15%.

Instrument of Test Result
The validity test in this study uses Pearson correlation, where if the value of Sig. < 0.05 then the instrument is declared valid. The reliability test in this study used the Cronbach's Alpha (α) > 0.60. When the Cronbach's alpha value was above 0.60, the instrument was declared reliable or consistent. The study shows instrument test result, such as validity and reliability tests with the analysis as follows:  (2022) The validity test results on table 4.2 show there are three questionnaire questions on the Digital Marketing (X 1 ) variable, and these three questions meet the requirements that can be said to be valid because they have a significant value of less than 0.05. There are three questionnaire questions on the Promotion (X 2 ) variable, and these three questions meet the requirements that can be said to be valid because they have a significant value of less than 0.05.
There are four questionnaire questions on the Service Quality (X 3 ) variable, and these four questions meet the requirements that can be said to be valid because they have a significant value less than 0.05. There are four questionnaire questions on the Repurchase Intention (Y) variable, and these four questions meet the requirements that can be said to be valid because they have a significant value of less than 0.05.
From table 4.2, the results from reliable tests show the Cronbach alpha value is bigger than 0.60, which means the data was reliable or consistent. It is also seen that the value of Cronbach's Alpha on the variable is greater than the value of Cronbach's Alpha if the item is deleted. So, it can be concluded that respondents' responses are declared reliable.

Classical Assumption Test 1) Normality Test
The normality test in this study was conducted using the Kolmogorov-Smirnov test method. The criteria can be seen if it has a significance value > 0.05, which means that the distribution is normal. The results of the normality test utilizing the Kolmogorov-Smirnov test method are as follows:  (2022) Based on Table 3.3, the normality test performed using the Kolmogorov-Smirnov test has a significant result of 0.200, so it can be said that the research data has a normal distribution.

2) Multicollinearity Test
A multicollinearity test is used to determine the correlation between independent variables in a regression equation. The measuring instrument used for the multicollinearity test is the Variance Inflace Factor (VIF) where, if the VIF value is < 10.00, then there is no multicollinearity. Here are the results of the multicollinearity test:  (2022) Based on Table 4.11, the VIF value of all variables is < 10.00. Thus, the study meets the assumption of multicollinearity free.

3) Heteroscedasticity Test
The heteroscedasticity test aims to determine the similarity of variance in the residuals. The study is said to be good if there is no heteroscedasticity. In this study, researchers used the Glejser test method to determine the heteroscedasticity test. When the value of Sig. > 0.05, there is no heteroscedasticity in the data. The results of the heteroscedasticity test are as follows:  (2022) Based on Table 4.12, it can be seen that the residual value of all independent variables has a Sig value. > 0.05, then it can be said that there is no heteroscedasticity in the data.

Hypothesis Test
A hypothetical test with multiple regression was conducted using the t-test and F tests.

1) Partial Test (t-Test)
A T-test was conducted to find out how much influence one independent variable has on the dependent variable, individually or partially. If the significance value (Sig.) < 0.05, the independent variable partially has an influence on the dependent variable. The following are the results of the t-Test:  Table 4.10, it is known that digital marketing has a Sig value. < 0.05, which means H 0 is rejected and H 1 is accepted. So, the conclusion is that the digital marketing variable has a partially significant effect on the repurchase intention variable. b) Researchers use the following criteria to test the hypothesis of promotion variables: If the value of Sig. < 0.05, then H 0 is rejected and H 1 is accepted. If the value of Sig. > 0.05, then H 0 is accepted and H 1 is rejected. Based on Table 4.10, it is known that promotion has a sig value. < 0.05, which means H 0 is rejected and H 1 is accepted. So, the conclusion is that the promotion variable has a partially significant effect on the repurchase intention variable. c) Researchers use the following criteria to test the hypothesis of service quality variables: If the value of sig. < 0.05, then H 0 is rejected and H 1 is accepted. If the value of sig. > 0.05, then H 0 is accepted and H 1 is rejected. Based on Table 4.10, it is known that service quality has a sig value. < 0.05, which means H 0 is rejected and H 1 is accepted. So, the conclusion is that the service quality variable has a partially significant effect on the repurchase intention variable.

2) Simultaneous Test (F Test)
The F test was carried out to determine the effect of the independent variables together on the dependent variable. If the value (sig.) < 0.05, then the independent variables simultaneously have a significant effect on the dependent variable. Here are the results of the F test using ANOVA:  Table 4.11, it can be seen that all independent variables have a significance value of < 0.05, which means that all independent variables of digital marketing, promotion, and service quality simultaneously have a significant influence on the dependent variable of repurchase intention.

Coefficient of Determination Analysis (R 2 )
The coefficient of determination (R 2 ) aims to measure how much the independent variable can affect the dependent variable. The coefficient of determination (R 2 ) has a range between 0 and 1 (0 ≤ R 2 ≤ 1). The bigger the value of R 2 (close to 1), the simultaneous effect of the independent variable on the dependent variable is considered strong, and if (R 2 ) is close to 0 then the simultaneous effect of the independent variable on the dependent variable is considered weak.  (2022) Based on Table 4.15, it can be seen that the coefficient of determination is 0.722. This shows the variability value of digital marketing (X1), promotion (X2), and service quality
