I agree
You cannot use the Groupon for happy hour. The Groupon is for dining in the restaurant. If you want to use the Groupon for the whole table, then all food should be on one bill. But it's best to read the fine print on the Groupon. I think there might be a house Cabernet for happy hour that is around $5 but you can check out the happy hour menu on their website.
