In Jacksonville for a few days and wanted Mexican food and El Potro was pretty close so we tried it. Our waitress could not have cared less that we were even there. They have a buffet and were almost offended we asked for a menu. The buffet food seems to have sat out all day. A refill really offended our waitress. We ordered beef nachos for our kids and it literally tasted like dog food, not joking.
The salsa tastes like it is poured out of a Pace Picante Sauce jar. I hate writing bad reviews but this place deserves it. I honestly cannot think of a worse dining experience and I travel a lot and I eat at a lot of places.
