We purchased the dinner for 2 on Groupon. It was our second time to do that and also at the same restaurant. Everything was great until the bill came. They charged us extra for $80 because of tip and services. We asked them to show us that policy. They said it is a requirement of the restaurant when we purchase on Groupon. There was no such policy from our first time there. I won't recommend buying on Groupon or going to this restaurant. It is such a rip-off. Every disappointed.
