If you're looking for quiet places, I like the Territory Lounge at WL, the Crew's Cup at YC, Martha's Vineyard at the BC, the Bellevue Room at the boardwalk.
Jellyrolls is a lot of fun, but it is loud and raucous, with the dueling pianos and singing along. ESPN is also fun, but there is constant noise from all the TVs with the different sports channels on, and at certain times (weekends I htink) they have a live DJ & therefore constant noise.
