    Although service overall was good, it was a little less formal than I expected. Everything was presented nicely and spaced out appropriately with drinks, apps, entree and dessert. My steak was excellent (bone in wagyu strip) and medium rare was spot on with a great sear. I was happy with the service, and never had to wait for more drinks, or anything at all, but I think that some might expect a little more formality from the waitstaff for a $200+ dinner for two, before tip. Also, could use a better beer selection if you are a beer drinker..
