China is known for its own cuisine all over the world, but one thing most cities don't have is easy access to good food from other cultures. Unless you live in a big city, what you'll get at most is a sad recreation by a cook who learned how to make "x" dish off of youku or similar YouTube clone site.
However, being in Beijing does offer some truly authentic restaurants if you know where to look. Example, this restaurant called Four Seasons (no relation to the hotel) which offers delicious Japanese food...and if you pay enough, it becomes all you can eat.
Here is a collection of dishes I ordered
Start off with some sake
Pan-fried Gyoza
Beef sashimi
Salmon sashimi
Braised eel
And of course....sushi
