Santa Maria has a very Latin temperament - it is in the most suitable area - Kreuzberg, where always happens something. The drinks there are great and people there are super friendly. The food is good, with the exception of lunchtime, unfortunately, during the day the food is cold, not fresh and not that tasty. I still would recommend this place for tequila shots and snacks.
Service in Santa Maria is great, young and friendly personnel, smiling and pretty fast and deft for that space :)
The atmosphere is the best thing of this place, built by design, personnel and target audience of this place - young and open-minded people of Berlin and its visitors. You have atmosphere when you meet and talk to random people, with lots of drinks nearby :) However if you need yout space both personal and physical - SM is not for you
Depends on the time, generally personnel makes everything to make it clean, however, the tables are not that tidy, especially on a rush time.
It is the most provocative and sociable place in its category (Latin American direction). This makes SM a bit cooler among places to spend with friends, however, it's not in the top when it comes to a tasty food. The design is my personal top1 among South American Berlin Spaces.
Pricing is very average for Berlin, Kreuzberg can be a bt cheaper, however it's a nice price-quality ratio.
