I don't know anything about how authentically Irish the food, decor, or general ambiance is.
What I do know is that ALL of the meat in this restaurant is sourced locally, and is pastured - in the case of the beef, it's 100% grass-fed. As someone who will ONLY eat local pastured meats, and therefore is limited to vegetarian or pescetarian choices in restaurants, this is an AMAZING gift! To be in a restaurant that goes out of its way to use these kinds of meats is phenomenal. To all those who complain about the prices - I guarantee you they are VERY reasonable for this kind of meat! ...and worth every penny, as far as I'm concerned.
They also use these great paper to-go boxes instead of styrofoam. I'm thrilled to support any business that goes that much out of its way to support the environment and other local businesses and small agriculture.
As far as the good goes, what we had was awesome. A couple of Irish coffees (one traditional, one Baileys) to get us warm after coming in from the cold weather, an appetizer of Irish nachos, and entrees were fish-n-chips and shepherd's pie... after the food was so fabulous, we had to try the desserts, even though it meant taking a lot of it home in the aforementioned boxes. The flourless chocolate cake was good, and the bread pudding was amazing.
We went mid-afternoon, so I can't speak to the crowds, since there weren't any. The waitress was awesome. The food was slow, as someone else mentioned, but we were warned ahead of time that it was all made fresh-to-order, so we were already prepared for that.
All-in-all, I highly recommend it, and we'll definitely be going back!
