New York City Sweets
There's La Maison du Chocolat at the Rockefeller Center, which isn't far from you. It's reputedly good, though I've never tried, since I don't love chocolate as much as many other people do.
If you like Japanese mochi or other Japanese desserts, try Minamoto Kitchoan on 49th, near 5th.
There's the Choux Factory at 48th and 1st, which is a lot like Beard Papa, except better. Choux are little spherical pastries filled with cream. It has a roving cart, too, though the location changes from day to day. You have to call to find out where it is.
If you like Indian sweets, Sukhadia's on... ooh, I think 48th between 5th and 6th has good ones.
There's Buttercup Bake Shop on 2nd Avenue between 51st and 52nd St.
I went to Kyotofu for both the daytime and evening and both menus have truly outstanding desserts! I've taken photos and wrote posts for each visit.
Have stayed at the Sofitel myself...great hotel...but must be honest with you...take a cab out of that area for the really good sweets...Go to Greenwich, for example, and visit Rocco's Bakery for some killer cannoli or practically anything there...Visit Jacque Torres Chocolate Factory, also in the Village...Grab a cupcake at Magnolia Bakery, or have a delicious cup of chocolate at Mirabelles...In my mind, the best "sweets" are not in that area...
