The Liberty is a great place with a nice beer and cocktail list. I've been here a number of times and have had a few different menu items, including burgers and special event menus. The special menus (Restaurant Week, Easter brunch, etc) are nice - you get a lot for the money and the menu items are different from the standard menu.
I 100% always recommend ordering the Salted Caramel Budino - its rich and delicious!
Atmosphere is very warm, cozy and beer-centric (its a gastro pub after all!) - good for a romantic meal or a group dinner (8-12 people).
I'd say the service can be lacking, depending on who you get - but nothing glaring, in my opinion.
