First off, the food was great. No complaints here. Appetizers were excellent, main courses were very well done. We left content and happy. The atmosphere was really nice with Brazilian music playing in the background, low lighting, and little noise. Definitely a romantic place.
However, if you're looking for an authentic Brazilian restaurant, this isn't it. I lived in Brazil for a year and a half. Sarava's cuisine is more new-agey with some Brazilian thrown into the mix. I would say that about 50-60% really traces its roots to plates from Brazil. The rest of the menu looks great, just isn't Brazilian. If you've got a hankering for one of the staples, like picanha, feijoada, farofa, or pão de queijo you can kill it here. Other touches though, such as vinagrete and brigadeiro were not to be found.
Regardless, the wait staff was extremely attentive and polite. Service overall was excellent. If I were back in the area I would return to Sarava.
