I came here for lunch and was pleasantly surprised . My friend and i  had the  $ 9.95 lunch special which had many choices. You can have soup or salad 1st then your entree. I had a wonderful tricolored salad litely dressed then I had a grilled chicken wrap with mozzarella cheese , roasted peppers, and  romaine lettuce with  aoli mayo. Delicious! I ordered a cappuccino  and it came in a large cup which was nice. Our waiter Joe was very attentive and pleasant. I can't wait to return for dinner.
My friend asked for a donation for our local fund raiser and they were only to happy to help with two $50 donations! That was amazing! Since it was my 1st time in!
I came here once with my coworkers for lunch and had the grilled salmon meal. I thought it was just okay. According to my coworkers who got sandwiches, those were pretty standard as well. The building and the decor is nice, with lots of TVs around the bar, and our waiter attentive and pleasant. They also have happy hour specials that we've yet to try.
Overall, the atmosphere was nice and so was our service, with the food being good but not exceptional.
I visited GrillStone on a Sunday night for drinks with friends. Prices were reasonable - $7-8 for a glass of wine and $4-6 for beer. Lots of choices for wines and good size pours. Big list of beers on tap too. They also have cocktails including a martini list. They did manage to disappoint with the Bloody Mary - my friend couldn't even finish 1/4 of the glass because it tasted so bad. We didn't have food but the menu looked good.
Atmosphere inside was nice. We sat at a hightop table near the bar - the bar itself was large. I could picture this place to be a great late night spot or place to watch the game. Service was so-so; we were greeted and seated by a older male in a full suit (manager?) but our waitress looked like she was ready to head down the Shore with her outfit.... And this is in December. The bartender also turned on all the house lights at 11:00pm to "change the mood". Seemed like a not so subtle way to say "finish your drinks".
All in all good drinks, decent atmosphere. Service left something to be desired.
