Naked Chocolate is on the U Penn campus. The decor is quite elegant. They have chocolate in all varieties: small chocolates, drinking chocolates, and cakes.
I had breakfast there: Sacher torte, chocolates, and coffee. The chocolates were great. I tried one of their spicy chocolates, which was very subtle and interesting. The Sacher torte was very good, but let me brag a little. I visited the Hotel Sacher in Vienna a few years ago as part of my extensive study of Viennese pastries (hellish work but somebody has to do it). Nothing can beat their Sacher torte. Among other things, they serve it mit schlag (with whipped cream), something that Naked didn't do. But I certainly enjoyed their version quite a bit.
It wasn't really a well-rounded breakfast. They have some muffins and other things but not omelettes, meat, etc. But what the hey, who can complain about chocolate in the morning?
