Delicious food and good presentation. The restaurant have a quiet atmosphere and nice low voice music.
Like most bars and restaurant in china, they have reasonably polite waitresses but undoubtely clumsy.
They have a wide range of vegetarian dishes. Try the potatos & vinegar dish, hard to pick with sticks but a great hunger-killer for a hard day.
Tourist prices but enough fair for quantity. About 9€ for 3-4 dishes and 2 drinks.
