Lunch at Topolobampo- Need reservations??

Hi all,

I'm headed to Chicago next week for a conference, and Topolobampo is on my list of places to hit up. My group of colleagues will inevitably be too unruly for us to do a reservation (can't say if 5 people or 20 will want to join) but I was hoping we might be able to grab lunch just walking in.

Is that too optimistic?? Our timing is a little flexible-- we can eat at 1pm after the rush in case that helps.

And thanks to everyone for their thorough reviews on previous discussions. I was able to nail down a nice restaurant schedule for the rest of the trip without posting myself.

Thanks!
