I was in Cabazon (outlet center outside of Palm Springs) last week, and found a store called "Le Gourmet Chef," that stocked a line of tri-ply stainless pots and pans that look identical to All-Clad. They have a core of aluminum between two layers of stainless, and even have roughly the same handles, etc. My suspicion is that All-Clad either manufactures this stuff as a second line, or licenses the patent or something, because there are repeated comparisons to All-Clad in the point of sale ads.
Anybody know anything about this stuff? It's markedly cheaper ($60 for a 12 inch frypan or a 6 quart stockpot), and looks to be about the same stuff.
