You could do worse for Mexican food, but you could also do better. The food here is okay--it's cooked properly, and they have a lot of variety in their menu. Their chips and salsa are yummy--their salsa especially is probably my favorite in town. My biggest issue with their food is that it's pretty bland. If I wanted really good Mexican food, I'd go to Taqueria El Porton instead. However, their margaritas are yummy and cheap! Expecially on Thursday nights, when they have margaritas on sale! Their staff is very friendly and the service is quick--it's easy to get in and out for a speedy lunch. The prices are very reasonable (even on margaritas, even when they're not on sale...) So, for a large group after work who wants some snacks and margaritas, Fiesta Ranchera is a pretty good bet. But if you're looking for a yummy posole or a terrific taco, there are better options.
Pros: Yummy salsa, yummy margaritas, yummy prices
Cons: Bland food
