There's really not a lot to say about Gaucho that hasn't already been said elsewhere, better. Great food! I always make time for a stop here when I visit Pittsburgh!
The wait times can be long, so go prepared. And by go prepared I mean look at Google. We went on 4:30 on a Thursday, and walked right up to the counter. I realize many may not have that kind of flexibility, but if you do then it really helps!
