The Food Store, operated by Wydin, sells a variety of fresh food, and is located in Port Sarim.
The shop plays a notable role in the Pirate's Treasure quest - it is the drop off point between Karamja and Asgarnia to find the otherwise illegal beverage Karamjan rum.
It is a requirement to start the quest to access the back part of the store. However, a white apron (which can be taken from the Fishing shop to the north) is the prerequisite to access the back. Each crate is notable of having an unlimited amount, albeit low-levelled, of food stock: cabbages, potatoes, raw chickens and bananas aplenty. If you are looking for a small bit of change, selling back Wydin's own stock can be useful.
