Es bastante modesto por su ubicación y apariencia exterior, ¡pero es maravilloso por dentro! Sin duda, es un lugar familiar, y siempre es un placer apoyarlo. Hay una tienda de comestibles española justo al entrar y un restaurante mexicano al fondo. Todo se cocina fresco y tiene precios muy razonables. Pedí tres tacos de carnitas y estaban deliciosos. Los llevé para llevar y los comí al llegar a casa. Todavía estaban calientes y la salsa que me dieron para acompañar los tacos también estaba buenísima; ¡la usé toda! Creo que por tres tacos pagué 10 dólares y valieron cada centavo.

This is certainly a family owned and operated type of spot which is always nice to support. There is a spanish grocery right when you walk in then a mexican restaurant in the back. Everything is cooked fresh and is priced very fairly. I got three tacos de carnitas and they were delicious. I took them to go and ate them once I got home.

We ate outside in the car and watched a woman walked up to a closed store/restaurant. She was quite disappointed that it was closed. She shrugged and laughed.

If a few people come in here it will be crowded. Very cramped and full of local Mexicans. Food menu is pretty limited. There's tacos. It's about $5 each. These are bigger than the fast food type of style. Have to say it's more like a convenience store than a restaurant to be honest. It's limited and it's pretty cramped inside. There's also lots of Mexican groceries and things.
