This is an interesting place. I've gone personally about three times. The first time I wasn't really impressed with it. But the second and third times were much better. It's always nice to give a new restaurant a second shot if they don't blow you away the first time around.
I've had the tartare and it was very good. But what really surprised me was the burger. Now it's not that hard to make a good burger, yet a lot of places seem to have trouble doing it. Hachoir nailed it!
The location is also great. And the coolest thing about this restaurant is the old operating room light that hangs over the kitchen. It's awesome! Just don't let your mind wander the way mine did. I try not to think of what stories that lite could tell;)
