Personal everyday bar favorite - RitterSport Marzipan. Get my fix when in Europe on business.

USA Bar/Cooking - Scharffenberger (http://www.scharffenberger.com/)

USA boxed - Forget Godiva, See's, Malley's. Certainly forget Russell Stover, Whitman, Fanny Farmer and all of those ilk. Another poster said no chocolate is better than bad chocolate - I agree. Best boxed chocs in USA I've found are Esther Price (http://www.estherprice.com/). Very fresh fillings made with fresh cream, eggs, etc.

Restaurant desserts - haven't been keeping track, but Chocolate/Coconut Pots-du-creme at FAHRENHEIT in CLE were excellent!

Europe - Belgian chocolates are ver, very good. Nice shop in corner of Le Grande Place, but I can't recall name. Touristy (off course) but good stuff. However, I am not a big fan of hazelnut, which seems predominant in Belgian products.
