I'm unexpectedly having to travel to Chicago tomorrow for work. I don't have friends in Chicago, but figure I might as well get a good meal out of the trip. I'm looking for someplace I can go have a great meal by myself, and where the fact that I'm doing this on short notice won't be a problem. I thought about trying to sit at the bar at Frontera/Topolobampo; is that likely to be hard to do on a Tuesday night? What other places would you recommend? Thanks!
