On the west end of the beach there's a little hole in the wall called Fiesta la Playa... it's west of Hooters, on the other side of the street, and has the 99 cent margarita sign out front. While waiting for our jetski run, we decided to grab a quick bite here. They are a very simple place with a small menu... the food is cheap, the portions as massive (I ordered a half order of nachos and ate about a third of the plate), and the food was really good and basic. Didn't have a margarita, but the beer is ice cold, and I would definitely revisit...
