The food didn't convince me enough to go back, because it does have some Korean taste to it and I don't like korean food.
The prices are super cheap and service is good and nice though!
I ordered both beef and chicken burrito, and asked for non spicy. However, it was still spicy to me (the red sauce that tasted like Korean), and I thought they gave me the spicy one so i went to complain. The reassured it was the non spicy one, and offered to make it again but I said it was OK (if it was already non spicy, not much they could do anyway).
Later they came to offer me an ice americano to help with the spiciness and I chose to get extra coke instead.
They were nice and truly concerned.
Therefore, i can't give them a bad grade. I think if you don't mind Mexican food tasting a bit Korean (fusion?), then this is a good place to go and save some bucks.
