Using a big residential house as an office for 3-12 employees probably gets you a great kitchen (most 3-4BR higher-end houses have better kitchens than most offices), which helps this a lot.
From what I've seen, you can get a chef 2 days/week for about $100 per day plus food costs to prepare food for 4 days (that day and the next day), and then do catered food (or a group trip out) to a specialty restaurant, at least to start out.
