> Biergarten
This is a beer bar with a solid list of craft beers selected by Brooklyn Brewery’s master brewer Garrett Oliver. It also serves German-influenced sandwiches, entrees, and small plates. This is quite possibly the best place to kick back at LaGuardia, and the food is surprisingly good.

> Custom Burgers by Pat La Frieda
Famed meat purveyor Pat LaFrieda helped develop the meat blend for the burgers here, which are made to order, and served “with all the fixings.” Plus they also offer milkshakes, made in-house.
