I tried this place for lunch one day, and it was... just okay.
I tried a cheese arepa and a beef arepa, after being told by the waiter that one wasn't enough for lunch. The beef was pretty good, but overall I was unimpressed--the arepas were unreasonably greasy and the cheese was chewy to the point of being almost inedible. Also I was not thrilled with the idea of paying $13 for lunch with no sides that wasn't all that wonderful.
I won't be back, but not because I had a terrible experience--I didn't. It just wasn't... good.
