It's all open. The vibe in northern NH is very chill. Everything in Coos County is wide open and they barely ever wear masks... (not saying that's a good thing).
In Grafton and Carroll counties, they have mask mandates in most places but most restaurants are open. Call ahead, as hours are very weird and don't match what you find on Google. Been burned several times already in Conway area. They suddenly close at strange times on strange days.
