Sadly, Beijing doesn't have a massive Cajun & Creole dining scene, and this is unfortunate because the food would be a welcomed addition to the extremely diverse culinary enterprises in China's capital city.
What Beijing does have, however, is a great range of restaurants where you can find bits and pieces of the Cajun & Creole spice and variety that you love so much.
Take, for example, the French elements in Cajun & Creole food, and you'll enjoy the cuisine at Jaan or Morel's, where the international vibe is fused into the cooking and you'll taste subtle varieties of southern spice in these northern fares.
The Seafood that makes Cajun & Creole food so famous can be found, in a different cooking methodology, at Blu Lobster or Hastsune. You're unlikely to find cajun spice, but if you have your heart set on seafood you can always pack your own spices and head to either of these fine establishments for a seafood dinner.
Latin American food is somewhat similar to Cajun & Creole cuisine, and you might enjoy the tasty treats at Mexican Wave. Again, the spices arn't as strong but you might find a decent substitute here.
Indian and Thai have slightly similar spices to Cajun & Creole food, and Phrik Thai and Mirch Masala offer great curries, spicy kebabs and even prawns, which are similar to crawdaddies.
