We ended up here by chance, we saw they had a Lunch Set Menu and decided to try it. Place was really cozy and very busy. All tables full and people taking to go.
Set menu was good and cheap, they had a few options but we went for the two tacos (one beef and one chicken) + rice + some guacamole. Very good.
Services is also nice, both the guy at the cashier and the waiter spoke Spanish. You first order, they give you a number you take to your table and they bring your food.
For what we saw in the menu, they also offered some Mexican beers and drinks too.
They even had alfajores (that is actually Argentinean I believe, but they were good too).
We looked at what other people were eating and everything looked very good, we actually wanted to come one last time before leaving the city but couldn't. For sure next time!
