Do they take credit cards

Debit cards.

They take debit Cards. They charge $3.50 per transaction plus they round up to the nearest $5.00 increment and hand you the change. ( example your total $42.00 w/$3.50 charge $45.50 then they round up so your total is now $50.00 and you get $4.50 change)

Debit only -- I would bring cash
