I like the idea. As many others have already said, I think approx. $10-15 per meal would be ideal.
Just a suggestion: I think you should really market this service to businesses and office-crowds for breakfasts, lunches, and dinners. My last office was in an affluent area where the walkable lunch and dinner options were Subway and 20 or so high-end sit-down restaurants. Killing an hour and spending $40 on lunch wasn't a viable option and Subway got old after about three weeks. I often worked from 7am-9pm and would have gladly paid $30-40 per day to have a breakfast, lunch, and dinner prepared and delivered to me to avoid the monotony of Subway, the price of "creative French fusion" cafes, or the time-commitment of a Steakhouse lunch - and I know I wasn't the only person in that situation.
