If you go, definitely get the guacamole! It is prepared fresh next to your table with the ingredients you specify. You could go just for that and some other appetizers or drinks.
The other menu items are OK. I also ordered the special seafood fajita dish upon a recommendation from the waiter. It was a nice concept dish (served bubbling hot in a lava pot) but it was a little too salty as prepared for my meal. Otherwise, it probably would have tasted great.
The veggie quesadilla was much better than the special fajita dish.
Overall, a nice place to gather with friends over guacamole! Did I say I loved the guacamole?
