The location had two things going against it... there was a large party which had taken over the main bar, as opposed to the open spaces in the back, and there was almost no service unless you were part of of this group. I waited over 10 minutes for the hostess (also the server!) to meet me and show me to our table. The hostess was overworked and surly, not her fault, as she was the only one who was supporting everyone who was not at the bar.
The Gryphon actually called me earlier in the day to ask if we (who had made reservations through OpenTable) would prefer to be seated at the bar... the same bar which was taken over by a private party. Not sure how that would work out for anyone!
This place does not belong on OpenTable as it is NOT a restaurant, and should not be advertized as such.
