I temporarily forgot about this article in @ChicagoMag a few months ago. We made reservations to check out the prix fixe menu next Monday at May Street Market. We'll get 3 courses for $25 AND it's BYOB. Sounds close to stealing. Anyway, other places on this list are definitely going to be considered in the near future.
