Probably my best meal in Vegas. Simple, creative unique food made from fresh ingredients. The prices are pretty reasonable. The place has a fast food vibe, and that's really the only downside.
Order a few arepas depending on which ones sound best. The beef empanada was a particular treat, as were the pork rinds and yucca. A huge meal for two comes in around $25.
You can walk here from the Stratosphere in about ten minutes.
