Are they cash only?

Yes. The sister brewery, mountain sun in Boulder, will take an IOU if you get desperate. I'd bet it's the same for Vine Street.

Cash only, but they have an ATM with a $1 fee

They're "cash only"

They will sometimes let you mail a check to them later but they also have the cheapest ATM fee around. $1 last time i used them. When I didn't have a local bank I would take out cash from them actually

Or local checks with ID

Yes

Cash or local checks
