It's been almost 2 years since I have been so I would hope things have changed. I don't remember there being many craft beer options especially at the tables. I would always bring my own beers and leave them in the room. No one said anything to me about walking around the casino with 22oz bottles and having them at the poker tables. The only thing you can't do is bring coolers up to your room if you are staying there. So pack all of your beer in a backpack.
Firewaters at the Tropica has a good selection. I don't recommend the Tun unless you want to be disappointed. If you can have dinner at Noodles of the World.
Head over to Mussel Bar at Revel; pretty soon when Revel closes you won't get the chance and they have good options.

The post from the vintage wine boutique is interesting. Seems like they are just learning craft beers and mixed some things up though.
