Vezpa is a New York–style pizza place in Leblon, with brick walls and high ceilings, where you can order pizza by the slice. The crusts are thin and crunchy and there are decent selections on hand – try the mozzarella with tomatoes and basil. Vezpa also has many other locations, including in Ipanema (on Farme de Amoedo) and Copacabana (on Djalma Ulrich).
Don't miss the self-serve artisanal beer (and cocktail) taps. They're a fun way to sample different drink options – in whatever size you want (100mL from R$3.50).
