My vote goes to LeCellier. I know I am not a part of the majority and it may have been just a "bad night", but last august our dinner at WPC was absolutely horrible. We frequent LeCellier and it was our first time at WPC. Each of us (my family of 4 plus 2 sisters and their families and our parents) were not at all thrilled with our meals. They were actually cold when we received them after a very very long wait.
LeCellier, we just love, the atmosphere, the steak, the bread and of course the soup! Good luck, I am sure you will enjoy whichever you decide.
