I'm actually going to be in Fells Point myself for New Years. I plan to spend at least the first half of the game nursing a hangover in my friend's living room, but I'm sure we'll be in an establishment watching the second half and the rest of the day's games. I would guess that that establishment will be Max's; I think that's where my friend usually goes to watch games. They've got a lot of TVs and one of the best beer selections I've ever seen.
If you've never been to Fells Point, you're in for a good time. My friend has probably 25-30 excellent bars within a five-minute walk of his apartment. Just make sure you have a pint and crabcakes at John Stevens; it may be the best I've ever eaten.
