This is a place everyone should experience at least once. The menu itself is hilarious, with some great names for items and descriptions as well. The service I've received in both of my trips here was very good and also more helpful than you would find in most places as they actually took time to explain some menu questions instead of just giving the quick answer I've come to expect.
The best thing I've tried is Big Gay Al's strawberry chipotle BBQ wings. As a big fan of wings, different flavored wings, and chipotle flavor these were an excellent mix of some really interesting things. The sauce itself is so good that I would use it on other menu items and not just the wings.
They also love bacon there. The bacon night sounds amazing, though I'm usually in town only on weekends and haven't had a chance to try it. They also have bacon dry rub flavored wings that are worth trying for any bacon lover.
If I was going to recommend a place to eat in Mount Washington it would be Shiloh Grill over the more expensive Monterey Bay Fish Grotto and LeMont, both of which I've experienced as well.
