Had the exact same experience this past Friday as Heather N did in her review on 4/30/13. We had $60 in prepaid gift cards that we legally obtained by some third party vendor. We paid the bill with them, the waiter told us they didn't accept them any more. The owner came out and could not have been more unpleasant, told us this was our problem and that if we didn't pay she would call the police. Not sure what the problem was, but apparently they no longer accept them; fine, but we paid for the gift cards in the first place and probably obtained them before they changed the policy.
The owner did offer us 10% of a discount, which the waiter actually had the gall to ask us if we really wanted taken off the bill. We said yes. He didn't honor. We were so distraught by the whole experience, we didn't tip. Not like me at all nor is complaining about a place, but the service was so horrendous and unacceptable, I feel no other alternative is possible. Nearly thought about contacting my credit card company to stop payment.
Not a chance I would go back, nor would I ever recommend anyone going to this place. Wouldn't do anything to support this ownership. Not how you treat customers under any circumstance.
