I ate there yesterday (21 Feb 2013) with my girlfriend. The place looks like a traditional Chinese store with a buffet and a shop mixed together. There's enough space to sit, but we decided to choose the take-away option. The food was not labelled and we had to ask which one is vegan. You have to speak Spanish for that, they don't speak English.
We had a box of 4 spring rolls and 4 small pasties (empanadas) and a box of mixed vegetables with 2 big steamed dumplings for 147 pesos altogether. Good food for a reasonable price, but there are not so many things to choose from.
Cons: No English spoken, Vegan food not labelled, A bit messy (for a western taste) store
