They have a happy hour that begins at 7PM and you can get a discount on all the food then. However, by that time most of the food is gone and there are only limited options, so it is only recommended if you are not very picky. The nice thing about this place is they have Latvian vegetarian choices such as vegetarian pelmeni, mushrooms, Latvian soups, etc. On weekdays, you can sit on the second floor and it is much less crowded than the first floor. If you want to eat dinner here, I recommend you go at around 5PM so you still have a lot of food options.
A big plus is that they are open on Sun.Pros: good food, Latvian choices, open on Sun.
