Barbie don't make stand alone food accessory sets. My daughter has a mix of Lottie dolls, Chelsea and Barbie and various baby versions and a huge Kidkraft house. She currently plays with some Shopkins food characters and makes some of her own food our of paper, and some random Playmobil bits from other sets. I'd love to get her a collection of miniature food, but just can't see anything suitable.
So far I've considered the Real Littles Mini Brand food, but it's more plastic packaging then food and a lot of American junk chain brands we don't even have here, and you don't know what you are going to get. Lundby have a cute dolls house set but it's a bit dull (salt, pepper, herbs not much food at all) and then there are lots of Ali Express style bundles without packaging and reviews usually say people received multiple duplicates, and the range is not good and they aren't very giftable.
There seems a huge gap in the market here. Toy kitchen food is readily available, but not for older children. Does anyone know any Barbie size dolls or figures that might have accessories I can look for? My daughter is 9 but very much into toys still.
