You can find Draft in the ground-floor of the Holiday Inn at 30 Washington St, Somerville MA 02143 at the Eastern edge of Bunker Hill. I stayed in this Holiday Inn for several days with a coworker while visiting my firm's Boston office. I normally would not have spent much if any time in the hotel bar but it doubles as the breakfast location in the mornings and interestingly, was recommended to us by the server at Tavern at the End of the World as a covert local, quiet watering hole.
The room is on the ground floor to the right of the lobby and is also used for breakfast in the mornings in an adjoining space. The breakfast buffet is nothing to write home about - more like the "freebie" breakfast you get at Holiday Inn Express (it's it odd how the more expensive the hotel, the more you have to pay for stuff that's free at the lower end?). I'm not sure if it's worth the $10 you pay if you order it with your room, but it's certainly a better value than the $13 you pay if you don't.
At night it transforms into a a cozy small full bar serving a decent selection of booze, beer and tavern food. There are multiple screens behind the bar so you can keep up with your favorite teams, or on the night we visited the Republican debate. This night I stayed with the very excellent Harpoon Take 5 IPA while my friend Sid had some low-end Scotch (my advice, stay away from brand you aren't familiar with).
I only managed to visit during one evening while in Boston but liked the feel of the place quite a bit. Service was exemplary and when we had an issue with the Scotch the manager came out, was very apologetic and took care of the problem for us. Kudos to the staff at this Holiday Inn and in particular Draft. I'm looking forward to visiting again.
