There is a 711 near Beijing West Railway Station. If you take the train, you will go there to buy a lot of food to take with you.

Shredded chicken cold noodles, spicy hot pot noodles, etc. are all delicious, but my favorite is the beef tendon noodles, which are smooth and chewy.

Rice balls and salads are both available.

It's also great to buy a steaming oden for breakfast if you go early.
