I love Si Senor. I live in the area and have eaten at Si Senor often since they opened (I'm not sure I can admit to myself how many times!!). It's an easy choice because it's casual, fast and inexpensive and there's something on the menu for everyone. The service is always good and I have never had a complaint about the food except for the fish tacos I ordered last year, which were a disappointment. I try to get something different every time I'm there . Si Senor provides generous portions and the food is to the table quickly. This is not authentic Mexican food. It's the standard American version of Mexican food so as long as you know that going in, you'll be happy.
