Los Altos is awesome! They offer fresh baked goods, fresh tortillas, hot kitchen, deli counter..and a whole lot more. Excellent prices on vegetables and fruits. The kitchen offers really good paquettas (meal packs) at great prices depending on the amount of people you are buying for. Authentic and much better than you'd get at an over priced Mexican restaurant. All prepared fresh..nothing frozen. They also offer free samples of the food you are interested in.
The staff is extremely friendly and helpful. Don't worry about the language barrier.
Definitely making this store one of my shopping places!
