So, did anyone actually go to lunch? Where? Are we doing it again? May I suggest Perry's, on Franklin between Randolph and Lake? It's one of my favorite places, and it's easy to get to for all, being so close to the El, and all, or by cab (or by foot for me).
I liked Hannah's Bretzel when my customary dining companion and I visited, but the sad fact there are only four chairs - not tables, chairs - pretty much rules it out for any manner of group, and it's too far from that overpriced park to even think about picnicking.
I'd love to try the original Heaven on Seven again - haven't been there in quite a while. Seating could be problematic, though - do they maybe take reservations for a group of, say, 6-8 or more? (and remember, it's cash only at that location.)
