For muslims I recommend:
Veggie burito, vegie tacos, and shrimp fajita
Drinks for muslims:
Virgin lime margarita (for two is good), virgin pinacolada
They have special fajita wednesdays, and sunday tacos( you can order coke as drink for sunday tacos because they asks you to order it)
They are also very friendly for groups. We were 18 and stayed for long on Sunday. they were closing at 11 and they did not even bothered us and we had really good time.
