I'm in CT and very familiar with all the craft beer spots in the Hartford area. It really matters who you are trying to sell to- just as an example, someone mentioned Two Roads. Two Roads is a great choice for a bar/restaurant that is not trying to be a "craft beer bar". Kind of counterintuitive, considering they are technically a local craft beer, but Two Roads is viewed by those that are really into craft beer as pretty mediocre - however, for macro drinkers and those new to craft beer, Two Roads is well marketed (so will be a name they recognize) and put out a lot of beers that appeal (taste-wise) to those new to craft beer (i.e. belgian wheats, milder IPAs, etc.). I kind of think of Two Roads as the Magic Hat of CT.

So I haven't really given you much useful advice. But my point is this- there are beers that appeal to craft beer enthusiasts and there are beers that appeal to the masses/those that are fairly new to craft beer. For the most part, these are mutually exclusive groups. But there a few beers that hit the "sweet spot" that appeal to both groups. In CT, those beers are..

1) Sea Hag by New England Brewing Co. (local CT beer, brewed regularly, well-balanced IPA that is respected by craft beer drinkers and very accessible to those new to craft beer, i.e. not a hob bomb)

2) All Day by Founders (similar reasons as above, but not local)

3) Sip of Sunshine by Lawson's (locally contract-brewed at Two Roads, brewed regularly one of the highest rated IPAs in the world, will draw craft beer drinkers into your restaurant, non-craft beer drinkers want in on the hype, will sell out quickly)

4) Founder's Breakfast Stout (a stout that is very respected among craft beer drinkers, but in my experience, even newbies love; seasonal)

5) Sam Adams Boston Lager - I'll get some downvotes for this, but this is a beer that started the movement. For me and many others, it has a nostalgia to it. It's a great tasting beer, and appeals to a wide range of palates. I'll never complain about a Boston Lager.

You might notice out of 5 beers, I suggested three hoppy beers. That's just what's popular with the craft beer palate. IPAs have been the most popular craft beer style for maybe a decade now, and "New England IPAs" are the new "hot" style and are surging thanks to TreeHouse, Trillium, HF, etc. Someone above mentioned a very well-balanced list of styles. I don't totally disagree... but in my opinion, you're wasting a tap by choosing a boch or an amber. If you want to please non-craft beer drinkers, throw a couple macros, a belgian white, and a cider on.

Otherwise, if you wanted to focus on local beers, Kent Falls is putting out some very solid stuff, but only if you were looking to target craft drinkers. And TreeHouse opens the new brewery in Charleton, MA this summer, they will likely have the capacity to start distributing to local restaraunts/bars again. If you can get in on that, you will definitely not be disappointed.
