After being regular customers since Ambience opened, we recently had dinner there and tried to use a Groupon type coupon to pay. My coupon clearly stated: 'No expiry date' yet they refused to honour the coupon claiming their promotion with Groupon was over. The problem is that I don't care. I paid for this in good faith and they refused to honour it. I lost my money. This is an inexcusable way to treat a long standing customer. I won't be back.
