Buzios is a solid 3 stars.
I got a groupon, and I'm glad I did. I got scallops which were pretty decent. My partner got the Miso Sea Bass which was eh. The cheddar mac was alright. The green beans were fantastic!! Now, the lobster bisque was pretty darn good. Pretty heavy, but absolutely tasty.
The bill without Groupon was about $130, which I don't feel the meal was worth, but Scott, our waiter, was really great.
I would be interested to see how their steaks turn out, but for what we got, a solid 3 stars.
