Ok, after much research I finally decided. I think we are going to go to Graze before we see Wicked at Ford. Wicked is at 8:00. Yahoo maps show the restaurant being 1 mile from the theater, but I have no idea what traffic is like on a Friday night in Chicago (I'm imagining the worst). If we want to get to the theater at 7:30 (taking a cab), and have a leisurely dinner with drinks and possibly dessert, what time should I make our dinner reservation for? Would 5:30 be about right?
Also, should we call ahead for a cab to pick us up at the restaurant at a certain time, or do cabs drive by frequently enough to just grab one?
