I've visited restaurants here in Hong Kong where everything is mock meat (usually tofu processed in some cunning manner, or fried gluten). From whole roast "ducks" to "chicken" skewers.
Some of the "meats" can look pretty convincing, though unless it's an unusually thick sauce, the taste and texture are different.
