Bar Pisellino is a fantastic all-day Italian style bar. They serve coffees and small bites and later in the day cocktails as well. It's a small place and you can't book a table, but you usually get a spot with little waiting. I wish there were more places like bar Pisellino!
This is one of my favourite places to go for breakfast/brunch! Their signature is housemade bagels with high quality smoked salmon. It's a large and vibrant place, always busy, so book if you can.
Maison Premiere is a fabulous cocktail & oyster bar in Williamsburg. It has a beautiful vitage interior and a very classy vibe. They serve cocktails, small plates, and of course oysters.
