I haven't seen much mention of Botequim on this board. We've been there twice, and found it to be excellent contemporary Brazilian. Delicious food, an interesting drink list, and Brazilian craft beers. A full report is on my blog:
Lightly charring the lemon slices intensifies their flavor and creates a gorgeous look for this delicious chicken dinner. Be sure to include any of the sweet, tangy liquid the lemons give off in the bowl; it adds incredible depth to the sauce.
