I do love to meet people here, but why?
The crepes aren't even that good.
The hot chocolate is grainy/sandy/nasty.
The servers are rude and inattentive, the tables are totally uncomfortable, and did I mention the disappointing hot beverages?
It's expensive too - especially for the quality (or lack thereof).
The kitchen staff are usually scowling (not good in an open-concept kitchen) and the wait staff I've experienced (over 4-5 visits) have all been grumpy and surly. As others have noted, there are frequent order mistakes and the service is notoriously slow... are these the same kind of crepes they serve on the street in Paris? It can't be! Those ones only take 90 seconds from ordering fresh to get into your hands... these ones take 20 minutes to prepare. Odd.
Anyway, there are better places in the city for crepes. This one just has the luck of a great location and lots of space to meet people.
