I'd agree - no worries using that All-Clad under the broiler. All metal and thick, so no worries about cracking (like with glass or ceramic) and it will take the heat (depending on how far it is from the broiler element, the top of the pan can see 750 - 800 deg F).
The only real substitute for a broiler is a flame, like a creme brulee torch (or propane torch). Or a salamander (basically a broiler element not in an oven).
