20% tip mandatory on groups of 6+. That's higher than typical elsewhere of 18% for groups, but I knew this in advance, so no gripe. When bill arrived 20% had been charged not only on food and bev, but also on top of tax! Was told "that's how the computer does it"--um, no, that's called gouging customers. If baseline service had been at 20% quality, a few extra bucks would have been fine. I'm happy to tip very well for great service. But service was not even 20% level. Very pleasant, but not expert. Repeat requests for things, plus salads brought WAY in advance of any hot appetizers, etc. Awkward. Been taken here a few times with a good friend who is a big fan; food generally good, but we shall give this place a little rest.
