I used to live round there - so here's a list of the things I crave lately - maybe you'll surrogate eat for me.
Cafe 28 is at Irving Park and Ravenswood - probably at your limit of distance. Can you have a Bloody Mary at lunch? Have a Bloody Mary at lunch.
Costello's Sandwiches is on Roscoe just west of Damen. If you go, please have the Mess for me. I've wanted one for days now.
Fizz is on Lincoln just north of Belmont. It's ok barfood ... except for the fried potato salad. The fried potato salad makes it all worthwhile.
It isn't glamorous, but Suzie China does dependable Chinese and they are not threatened by special requests or ordering not on the menu. Plus, they have lunch specials. On Lincoln, south of School.
Fernando's on Lincoln, south of Addison, is also not glamorous. They're a neighborhood standby with great comfort Mexican food.
If all you want is quick lunch on the run, try the Burrito House on Lincoln at Addison. The tacos are where it's at. At least, I think they're good - I've most often had them at 2 in the morning.
Have fun at lunch
