I have several "go to" places where I lunch regularly in that area, places with excellent food and are nice places to relax and chat:
Taste of Thai1029 W Golf Rd
Hoffman Estates, IL 60169
(847) 490-9994
Salsa 1717 W Campbell St
Arlington Heights, IL 60005
(847) 590-1122
Lou Malnati's Pizzeria1050 E Higgins Rd
Elk Grove Village, IL 60007
(847) 439-2000
Keep in mind that you can phone in your pizza order and they'll have it ready when you get there, if you don't want to wait 30+ minutes while seated for them to bake you a deep-dish.
There's also the excellent
Shaw's Crab House, right next to the previously-mentioned Big Bowl in Streets of Woodfield, but it's more upscale and pricey, probably not what you're looking for.
