Definitely get the mac n cheese. My favorite taco was the pork. It's filled with a good amount and it's really juicy. We also tried the chicken, chicken apple, chorizo, and steak. Also, the agua fresca is so refreshing!
Only gripe is the wait time for food. We waited over 40 minutes to get food. So my suggestion; order chips and queso so you have something to eat while you wait.
