My coworker introduced Unimarket to me. They sell a small amount of vegetables, frozen food, dried chilis, baked goods, general groceries, meats and they have a little cafeteria in the back of the store. Most people come here for the cafeteria - tacos, burritos, and other cool dishes, like fried meats.
Unimarket makes the best guacamole in the city. I don't know how they get the guacamole so smooth and creamy, but still in chopped up cube form. The flavor is unreal. It tastes so vibrant. The chips we got were freshly fried. This huge cupful of guacamole and chips only cost $5.00. One of the best deals in town.
I've tried the tacos and quesadillas. I prefer the quesadilla because the tortilla is crispy and I like the simplicity of the cheese and chicken. The tacos are the real deal and taste more authentic than the ones I eat in Cabos/PV.
