We've tried to avoid going to Brasa for a while now - unfortunately most of the reviews from friends didn't put it in the best of light, especially as compared to Chamas. However, we were recently in the Briar Creek area, and to our dismay, found TQ Zheng closed (a reasonable Chinese restaurant). Searching for a quick lunch, we found that Brasa had a buffet lunch for around $12 for hot and cold bar; $18 or so with four cuts of meats; $20+ for the "full" experience. As we were early, only a few others were seated.
The salad/cold bar was mildly above average; some reasonable pastas/ potato/ chicken salads; nothing extraordinary. The hot bar was not unreasonable, with a few different chicken dishes. Probably the best dish was the chicken stew... and the others were a bit bland, though probably sufficient for a good lunch.
I was excited about the four types of meats - in particular the bacon wrapped filet. The sausage was reasonable. But, the other meats all were a bit tough and just had an old, not very fresh taste to them. As one might guess, I was rather underwhelmed by the experience. Any steakhouse lives and dies by the quality of the meats that they serve - and it was clear to me that Brasa was unwilling to serve meats that would live up to its name.
Try it for lunch if you'd like... good luck on dinner. There are many other choices in the area - and for that price with that poor quality - I'd rather just buy a steak and grill it myself.
