I will be making a trip from Philly to the Midwest to visit my girlfriend's family over the holidays. We are headed to Chicago for a couple days to meet a friend and will have only one real day in the city. I will have to get some quick bites for lunch and will just grab whatever looks best and closest, but being a huge food lover, I am looking for a casual place ( will have been walking around all day, no time to head home to change from jeans) with great food that is signature Chicago. I have a reservation right now at Publican. It is a little out of the way for where we will be earlier, but I love Paul Kahan. So is Publican my best bet? Would love Avec, but was a little hesitant because of the no res policy. Going on a Tuesday Jan 3. I am leaning toward Publican, but also considering Avec, Girl and the Goat, and Purple Pig. Any advice appreciated. Thanks!!
