Can players go to town and drink potions?

If so how many potions can they drink?

Right now I only let players shop in town and rest.

Thanks for the help.

Assuming you are not playing an Advanced Campaign expansion, yes. Being in town is only a very little different from being in a dungeon - they can do most things they can do in a dungeon while they are in town.

Each turn a hero can only drink one potion - it makes no difference where the hero is (town or dungeon), the limit is one per turn.
