Nowhere else in Germany can you find 3 big market halls where you can buy Asian goods. Indian…read moresaris, fresh durian (!), small appliances like rice cookers and of course, every spice, vegetable, seafood you associate with anything Asian.
Dong Xuan mostly specializes in Viet items, but make sure to shop around to compare prices. We shopped for ingredients to make Filipino pansit and they have everything here.
Don't be shy to ask questions and be LOUD -- just like in Asia.
