Treinta y Seis close to Schlesi is a not too bad Mexican restaurant. I like to go there from time to time for lunch, it won’t blow up your mind but the food is more than decent. The staff is very friendly, the service usually quite quick, it’s cheap, with special prices at lunch time. I really like their enchiladas and quesadillas (even if I find strange to read quesadilla de queso since a quesadille is per definition with cheese…) The nachos are also a hit, the steaks are pretty tasty and the different sorts of baked potatoes really nice too.
They also have sandwiches, pastas and burgers, I’ve never tried them but they seem good, according also to some friends/collegues I went with.
