Well, during my honeymoon we did try out Stomp in Calistoga, located in the Mount View Hotel. We had earlier eaten at the French Laundry and Tra Vigne, so my opinion my be a little jaded, but I was not impressed. We both ordered the Filet. Mine was overcooked (ordered medium rare - no pink showing). It was tasty, but not a $40 steak. Also, while the staff tried to be upscale to coincide with the pricing, they failed. Our waiter was young and knew nothing about wine pairing and seemed to be a high school kid looking for a paycheck.
Not impressed at all. Many other options in this price range which would rank way above Stomp.
