Sur La Table is my guilty pleasure.
If the kitchen is my laboratory, Sur La Table is my ACME Catalog. They've always got something cool and new to check out, the prices are reasonable, and the staff is great.
Not only are the employees friendly, but more often than not they've got great suggestions on things to check out or how to make the most of what you're buying. In a world where most retail lackeys are sacks of flesh paid to punch buttons, it's refreshing.
The store's not huge, so they may not have your current object of desire. They're more than happy to order it, though.
