Check google for what's around you, if hours are questionable on google, just call and ask if they'll be open. Don't have high standards. NH has a few small cities in the southern portion with nightlife. Outside of that, it's very sparse.

Also, Lift and Uber is sparse even in its cities, and its DUI laws are strict (you can get a DUI below .08), so make sure you have a DD and stay safe.
