Unfortunately they put lettuce and tomatoes on it, and I am allergic to tomato's. I called back and just explained the situation, I didn't want to blame anyone just simply stating perhaps I misspoke or it didn't get written down. I was informed several times there's nothing anyone can do, and I'd have to call back tomorrow. I said I am not trying to file a complaint or even get a refund, I'd really just like to pick up a new burrito. She reluctantly agreed. When I arrived, she decided to reprimand me further about my etiquette and how long it took me. The remade burrito itself was 1/3rd the normal size, poorly made with nothing inside. If they make something this simple turn into this big of an ordeal, and then deliberately give me a poorly made burrito, almost 4 inches shorter than the standard I paid for out of spite, what else did they do to it? For obvious reasons, It went right into the trash. I would like to point out as well, after tipping 20%, this burrito was just short of $17. Whether you live here in town, or are just passing through, I would definitely spend your money elsewhere.

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. Si estás en Lake Geneva y se te antoja comida mexicana sin arruinarte, sin duda te recomiendo venir aquí y descubrir uno de los secretos mejor guardados de la ciudad. i am writing this in spanish and english so whomever reads this will be able to understand my thoughts. This is a small whole in the wall type of spot. It is rather unassuming because of its location and appearance on the outside but it is wonderful inside! 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. They were still hot and the salsa they gave me to go with the tacos was awesome too I used all of it! I think for three tacos I paid 10 dollars and they were worth every penny.

Actually it's more like a convenience store than a cafe. This has a dining area, so you can eat it here or take it wherever. About the most authentic Mexican food you can get around here, super authentic. It has the area to order food in the back. There's a dining area with a few tables. 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.
