I've been a number of times and the food is always excellent. On my most recent visit I had lamb and lentil soup, with a small cheese board on the side. The soup was gamey-salty heaven! I've had the mac-n-cheese, which is also great, and an ostrich burger which I had no expectations for (I'd never eaten an ostrich) but it was very tasty.
The inside is rustic and interesting, and the patio is great: they put a yurt on it now (alas, no fermented yak's milk to drink), and in past years have turned it into a skating rink.
The service has been better the last few times I've been. In the past, I found it was too cool, and steeped in irony. Examples: one of our group ordered a Caesar, and the waiter's response was "that's a pain in the ass to make." I ordered a Guinness, and then my friend ordered a Guinness too, and the waiter said "oh, you're original." I realize he was joking and well-intentioned, but I went there with friends, so they can tell me jokes....and my friends' jokes will be funnier if you just hurry up and get us our drinks. I don't dine out to be entertained by the staff... but I guess some people do. That said, everything else about the place is so good that it's worth enduring an aspiring Don Rickles. And, you get to sit in a YURT!
