Catering Work Lunch - KC
You should try Twenty20- (816) 471-2020. It's in the Crossroads, but they have some awesome boxed lunches and catering items.
We also use the Classic Cookie sometimes which is also very good. http://www.theclassiccookie.com/.
There's a Cupini's in Westport, I bet they could do it for under $8 a person.
