I live on the other Side of the Notch from N. Conway. Sleigh Rides at Nestlenook, Wildcat for skiing, Mt Washington snow coach. Rent a snow machine if you are bold and if we get a decent amount of snow over the next couple weeks. Ice Fishing, ice castles at suggested above.....
There is an escape room in N. Conway that's neat, food wise I like Horse feathers wings, Jalisco's for cheap and fast American type Mexican food, Delaney's has a good burger, Barley and Salt has lots of beer on tap but the food is a little high brow for me....but they have a good pretzel if you want to grab a pint and a appetizer, Merlinos is pretty good. And Moat Mountain is good for BBQ and local beer.
Tuckerman's brewery in Conway has board games and corn hole boards inside, that can be a fun, play some games and have a couple beers. Green Mountain Rifle barrel Company is in Conway, make sure you check out the blem section.
