"If you’re new to Chicago (or missed his statue carved into a mountain on your flight in), you might not know Rick Bayless. OK, we’re kidding about the mountain, but he is very well-known and he has a lot of great restaurants, including Frontera Grill. Xoco is another one, and it specializes in delicious tortas, along with other Mexican dishes like tacos and caldos. In case you don’t actually have to go back to work after lunch, you should know that they serve alcohol here, too." - adrian kane
