I've been going to Macayo's Depot Cantina since college and its a great place. Friendly people, great food, and some good specials you can't find at other locations. They have some really good margaritas too!
I go there for lunch at least once a week. The specials change daily for lunch so you can mix it up. I love the chips and salsa they bring out when you sit down and our orders always come out quickly. You definitely leave full!
They also have a great happy hour that my friends and I go to on Fridays.
