Purdy's is the second largest chocolate dealer in the country, with reasonable prices on a wide variety of chocolate items. I'm not the biggest chocolate fiend in the world, but I find Purdy's chocolates not too rich and a few won't leave you with a sick feeling in your gut. Good selection, too, with just about every popular kind like orange, white chocolate and caramel with a few wildcards like the "hedgehog" and the "snowball" which are worth a try....
Purdy's actually has decent ice cream as well, though they don't talk about it as much.
