I know that DAZ has a really nice diner set which has a lot of accessories that would help, from ketchup bottles to booths. It's inexpensive as well. I think I've seen a chief's hat around, but I'm not sure that's what you're looking for. Aprons would depend on which character you need them for. There's some maid outfits around, for sale and free, which could be used for waitresses and female cooks. I think I've seen an apron or two for free, but I don't remember where. (Sorry.) If you have V3 and the morphing dress, you could make a texture to turn the dress into an apron. Hope this helps, Cres
