Finally got a chance to go. Happy hour is totally worth it. Our steaks were done pretty well. My wife got the ribeye and I got the NY Strip, and after having a taste of hers I wish I'd ordered the ribeye. My garlic mashed potatoes were better than my wife's truffle crispy fries (which weren't very crispy, to be honest) but those were still tasty. The littleneck clams appetizer was awesome.
No surprise, the cocktails were dead-on, and the donuts for dessert were freshly made and perfectly cooked.
All in all, I think it was worth the wait. I would bring friends here for drinks, definitely. I'm not sure I would feel so good if I were paying non-Happy Hour prices for the steaks, but with such a long and generous happy hour that's not really a problem.
