We went out with another couple last night (Andrew's girlfriend's parents!) to Holy Grail. It was great.
We waited 30 minutes for a table which they told us. The bar is big and plenty of seating if you want to have a drink there.
We were seated on the first floor; they have a 2nd as well which I didnt see.
The food was very good. We shared the 'special' app of onion rings which were very tasty and also fried mushrooms. The guys had sirloin tips and we gals had boiled dinner and pan seared scallops (from the app menu). I loved the scallops; also had onion soup.
We had desserts too...KJ had pb pie and I had key lime pie but I was so full that I took it home and havent eaten yet.
Definitely would go here again. You can also get 1/2 off gift certificate from this site: http://www.goodeatsnh.com/index.html
