I'd recommend checking out The Portal in Manchester as another option, they host a lot of gaming nights. I know they do a "Learn to play D&D" night every Wednesday at 7pm, which might be a good place to meet other players even though you're experienced in the game. They might also need more DMs to fill in or expand out to more tables. They also host all day RPG events from time to time, so following them on Facebook would be a good idea.

Most Excellent Gaming in Manchester is also a great little shop, mostly focused on card games but they do sell board games and host a D&D night on Wednesdays.

Tabletop Gaming Center in Newington is a good option as the other comment stated and I know they were looking for more DMs as of mid January to host games on Wednesdays/Thursdays for D&D and Tuesdays for Pathfinder.

Cheers and welcome to the area from another nerdy central CT resident.
