52 Greenwich Ave.
Gottino is the cutest Italian spot tucked away on Greenwich (btw Charles & 10th St.) that serves as a wine bar but has a commendable brunch menu and very reasonable prices. They have a bar inside that probably first 10-12 people and then a quaint outside area with five or six tables. The brunch menu focuses on egg dishes and little toasts/sandwiches while the dinner menu is mostly meats/cheeses and a few small bite dishes.
It gets busiest during the weeknights but brunch never gets too crowded.
