Can Ting, Royal Mansion, Koko Bao Bar, all expensive. All the good Korean places- expensive. The even vaguely authentic japanese- expensive. The all you can eat korean barbecue have gone up a LOT as well.
Imported anything is expensive. Imported cuisine, which requires special knowledge and ingredients, has never been cheap.
Mian is still a good value, though the menu is limited, but very authentic.
