There was a restaurant supply shop (don’t know the name) in Taipei, on Min Zu East road and Chungshan North Road, between the 7-11 and Queen Burger. It moved not too long ago. The “shop” looked a mess, but that was because their primary business was restaurant supply, not retail. They just piled overstocked stuff on shelves in the storefront.
Does anyone know where it moved to? It was the only place I knew to buy Best Foods mayo. You could also get several varieties of American pickled peppers in Jars. The hot, but not too hot types.
