Ate here on Saturday with a groupon and gotta agree with Lauren M. If you want good Brazilian BBQ just go to Texas de Brazil. Its not that this place is bad, its just put to shame by Texas de Brazil. Atmosphere here is more like buffet, while TdB is upscale restaurant. You could impress a date at TdB not Pampas. Service was about equal, but i don't ask for much at Brazilian BBQ, just stop by with meats frequently and don't leave me waiting when I am ready to go. Both places accomplished that.
Ultimately the meat is what really differentiates the star status for these to for me. TdB just seemed fresher and better cooked. Most of my meats were overcooked at Pampas here. At TdB the meat guys (is that what they are called? Eh I'll go with it) at least tell you if meat is cooked med. rare, med. or well done. At Pampas i was left guessing with most of them seeming well done, while I am a medium rare fan. The only thing cooked proper to me was Pampas's Sirloin. The filet, lamb and everything else was all over cooked. Also Salad bar is better at TdB.
I would say it was worth the discounted price with groupon but I would not pay full price when i could add a couple bucks more to go to Texas de Brazil.
