I've been to both many times (there used to be one on Clayton but check out the one in Kirkwood). The atmosphere is so friendly, we even met the owner! The food has always been great, you can choose from a three or four course pre-set menu that is offered for an amazing value. I have gone with and without reservation, but have never waited more than 20 minutes to be seated, even when it seems full. I dream with the lamb shank! but have tried many different dishes (including snails) and it never dissapoints. Everything from apetizers, salads, main courses and desserts looks carefully prepared (and I am not even getting paid for the advertisement, I promise!).
Pros: Amazing food
Cons: None at all
