Came here with couple of friends last week. The place was quite empty on an early friday night but filled up pretty quickly.
I have been to le papillon on church street in the past and was quite surprised they moved to Front street. This place is nicely decorated and service was good. Between four of us we had four appetizers I think the mussels were quite good. My onion soup was nothing spectacular. My hubby liked his rib eye. I have to say my bouillabaisse was quite bland. Overall, we had a great time here (2 bottles of wine helped.) The final bill was quite reasonable for four people including 4 apps/entree + 2 bottles of wine it was only around $200.
I would give 3.5 star for the food and 4 star for decor/service.
