Hello! Are there any food stores with international products in Beijing?

You can find many big supermarkets such as Walmart, Metro and other ones in the city where you can buy international products.
If you want to try international food in restaurants, you can go to Sanlitun area to find different kinds of food.

Hi Kate,
for international products(food) you can try April Gourmet & Jenny Lu's both at Sanlitun and if you would want them at less price with more quantity being the criteria then u must try to find the San yuan li market and then there is always Carrefour, Walmart, etc for your basic requirements
