I went there after reading all the good comments on this page, and I was pretty disappointed. Mostly because I read the tenants are from Bretagne. If they were Chinese, well, it would be a little success.
1) If there's one thing i can't accept, it's the lack of fresh butter on the top of the crepe (usually added just before service, so it's still melting when it comes). Butter is not hard to find, it's not expensive.
2) The salad is served in the same plate, wich makes the whole crepe completely ruined by the vinaigrette.
3) The fillings are way too "wet". The should put less tomatos, less cream, less cheese, and let them cook open a longer time.
4) The salmon crepe is almost un-eatable : the crepe is fully wet with lemon and I felt like eating a salmon, cream and lemon soup with a few pieces of cooked pancake floating around.
5) The 25rmb cider cup is filled with the most untasty cider I've ever drunk.

But, for a reasonable price (though to eat to your full belly and drink some you need more than 100), it's ok. The best we tried was not the Bretonne but the one with cream, cheese, ham.
