I agree with Amor del Alma, and if you allow me to add, there is an application (app) called Groupon that if you search in the "restaurants" section and put the name of this one, it offers up to 50% off. I recommend it
The price is reasonable. In the afternoon it is a little bit more expensive. I guarantee you will like it ...!
For dinner we paid $32-$37 per person depending on the drink chosen. This includes unlimited trips to the parrilla and salad bar. You can also ask for pan, pure, papas fritas o empanadas. I don't think they charge for those sides either. It's a great place to eat with a large group or if you have a big appetite. I recommend you go try it out.
