A bit of culinary history
I can't help but be awed by the history of the place - going back to the times of Cafe Anglais. The view from the dining room is also superb, overlooking the Seine and Notre Dame.
The wine cellar, with its 500,000 btl collection, is enough to floor most people. The wine list looked like a volume out of an encyclopedia even 10 years ago, and clearly has improved as the collection has grown.
My favorite remains the Foie Gras des Trois Empereurs, where silky-smooth foie gras with black truffles is scooped out of a bucket with a dinner spoon, and laid out on the plate before you. It is hands down the best foie I have ever had.
The specialty of course is the caneton, which are shared by two people. You each get a little card with the history of the pressed duck, imprinted with the serial number of your caneton (since they started numbering them years ago).
Despite its recent decline in status (downgraded to 1 star by Michelin), I still consider La Tour d'Argent one of my favorite places in Paris.
