I found out tonight that eating dinner at the recently opened Le Pain Quotidien on Clarendon Blvd is definitely not worth it. Very overpriced, slow service, and unsatisfying dishes.
I chose the Roasted Turkey Tartine open faced sandwich, it was ok but not worth $10 and I was still very hungry. The lemonade is so super highly concentrated its hard to drink. Plus the food is served on cutting boards instead of plates, which always results in a messy table as it can't contain the loose bits.
Unless you are going there for their bread or breakfast pastries, stay away.
