I was just treated to a really good dinner at the Madison Concourse restaurant, Dayton Street Grill. The restaurant has a new chef since the last time I was at Wiscon (and according to my dinner companion, since last year). It's definitely more than "a convenient hotel restaurant" now, at least for dinner.

They serve three sauces, out of a list of twenty, with each entree. You can either pick your own sauces or they will recommend some. I went with their recommendations and was happy.
