I've been to Petite Thuet a few times now. It's conveniently located in the heart of the financial district. You no longer need to trek out to the edges of downtown to find some great pastries. Petite Thuet makes some excellent chocolate croissants. I don't think they are on par with what you get at Clafouti, but they are still pretty damn good. The place also makes some pretty killer sandwiches. I had a Lobster Salad sandwich recently -- a bit pricey at 9$ -- which was particularly good. Finally, they also make a mean americano.
