My son was studying about Mexico and then he wanted to eat in a nice Mexican restaurant. That was the reason why we went to Si Senor (Moema branch - Al. Jauaperi, 626). We simply enjoyed so much that we returned to the restaurant many times. They recently revamped their menu but you can still find great tacos, quesadillas, enchiladas and fantastic deserts (our favorite is their Oreo Cookie Ice-cream and churros). The restaurant is clean and the servers are helpful. If you like rock'n roll and blues and classic rock, you will love the soundtrack of the restaurant (for some people, it could be considered loud - it is not that loud that you need to yell to the person in front of you, but it is the right volume for you to listen the music). I recommend this restaurant if you want to experiment a well prepared Mexican food (I travel few times a year to Mexico and I can tell you that Si Senor - Moema - has a true Mexican food taste). I always went there for lunch. Be aware that the street of Si Senor, Moema (Al. Al. Jauaperi, 626) is locked Sundays due a public market that is mounted in that block of the street - you need to arrive there after 2:30 PM if you want to park in the parking lot - in any case, Moema is a safe neighborhood and you can park few blocks and just walk).
