Why have I never been in here before? Walking around Union Square today I stumbled upon a small restaurant supply shop, Broadway Restaurant Supply. It's not as comprehensive as the places down on the Bowery, but the advantage is that it's not down on the Bowery. In fact, it's right across the street from Rainbow Falafel. They've been open since April. Decent selection; lots of odd things you never thought about before (oh, so THAT's how they mass-produce fresh-cut French fries...) I have a jones for steel rings that I use for cooking or stacking food (think a teeny omlette)
The common items I saw were 10-25% cheaper than at Bed, Bath & Beyond. Worth a stop. Hours are generally 8a to 5:30p.
