The Chocolate Room is a new cafe serving hot chocolate, coffee and chocolate desserts; I believe they also sell handmade chocolate bars and chocolates. I tried the bittersweet hot chocolate ($4), and while it could have been a little more bitter for my taste, it was quite good, with a more liquid consistency that I prefer (unlike the Jacques Torres pudding-y texture).
Although it's only been open since Wednesday, the place was almost full. Desserts going by looked nice, with great presentation. The place is well-designed and cozy, service is friendly.
