I'm in Smithfield for a couple days. I've hit B & C (http://www.beeradvocate.com/beer/profile/12862/). It deserves its world class rating especially for this area! I'm looking for a place that sells single 12 oz bottles though... I'm not willing to commit a full night of drinking to an unknown six pack. Oh, and by the by, I've brought up a decent assortment of Swamp Head beer if anyone's around and would like to share with me. My wife and I are leaving Tuesday morning.
Best Prov options for singles: Nikki's: https://www.facebook.com/nikkis.craftbeerfinewinespirits [beautiful new store w/ many cold singles] High Spirits: https://www.facebook.com/highspiritsliquors and yep, B&C is great!
You absolutely owe it to yourself to pay Nikki's Liquors a visit. They just opened at the new location on Branch Ave in Providence and are actually having their celebratory re-opening this weekend. They have over 1,000 beers all lined up as singles if you so wish to buy em that way. Dogfish Head tasting tonight. It's definitely the best beer store in the area. I'm actually on my way there in a few minutes... This weekend: 15% off single bottle beers 10% off 6 pack beers 5% off 12, 18, 24, 30 pack beers.
Definitely go to Nikki's this weekend. High Spirits is less than half of a mile away. Hit them both. Anything quality that Rhode Island is going to get is going to be in those two spots.
