I LOVE this place. I've been a regular here since I discovered it 5 years ago. I've found that it fits almost any occasion. The daytime menu is light, inexpensive, and delicious, while the dinner menu is a but fancier with a more elegant atmosphere. The upstairs bar (my personal favorite) is very laid back with a great selection if drinks. During the summer months, the upstairs patio is host wonderful live music that can be heard all throughout Midtown.
I've literally visited hundreds of times in the last 5 years and have never had a bad experience. I recommend Cafe DO Brazil to everyone.
