We're hosting a family lunch & the idea is to get food of a "nice picnic" sort - nothing special - delivered to us. (For various reasons, we'd rather not do a "collect yourself" system unless absolutely no alternative.)
Waitrose Entertaining would have been ideal but they don't deliver where we are - only have the collection service. M&S similarly are collection-only for their party food service. Sainsbury's & Tesco don't seem to have a party food service at all.
We're in London.
Any ideas?
