I was at the Bucktown Soup Cafe not long after they opened, maybe a couple months back. The owner was there and told me he'd gone to law school in New York City and, after coming to Chicago, he missed the NYC soup joints he'd subsisted on as a poor student. So he opened one. I had a sweet tomato soup and something called, I think, a gumbo-laya, which was pretty much the hybrid the name implies. Both hit the spot - the gumbo-laya even packed a bit of heat.
I will say, though, first-timers might be a little taken aback by how spartan the place is. When I was there there was almost no decoration, the barest hint of signage, and the beverage selection started and stopped at water. They sell soup, period (oh, and it comes with a little side of good bread). Still, they're nice folks, the soup's good, and a couple of times it's been a healthier lunchtime alternative to a cheeseburger at George's, just a few doors to the north.
