Thx MostPost. Actually I am not sure about the Terrace Cafe on Fridays (if everyone doesn't mind the extra couple of $ that may be the best option if it is available)...nor how far in advance we would need to be there Friday to grab some tables.
I am sure others who know will chime in here. I can call the track and find out more as well.
As for dinner, my wife suggested the following as moderate cost options for dinner. I do want to be considerate of those who may not want to spend too much on dinner (open to other suggestions and comments on these):
[a] Jameson's - Decent food, moderate prices, I'm pretty sure they could handle a group.
[b] On Euclid there isn't much, Johnny's Kitchen & Tap could work, but it's farther. Jameson's is right off 53.
[c] Portillo's, while not fancy, has the consummate chicago Italian beef and sausage as well as burgers and I'm pretty sure they serve beer and wine. Also very close to 53 on Dundee.
[d] Up Rand Rd in Deer Park is Biaggi's, they could probably give you space. [e] Also Lou Malnati's inBuffalo Grove, right off Lake Cook, easy to find. Great Chicago
pizza as well as other Italian food.
