We learned about this from a coworker who learned about it from Jen Kelly at the New Pioneer Square blog, and now we’re passing it on to you.

Tat’s Delicatessen, which often draws a crowd during peak lunch hours, has a camera on its website pointed at the line in front of the counter, so you can check out the wait before deciding whether or not to go get a sandwich.

But don’t get your hopes up, home-computer creepers. You’re unlikely to catch anyone misbehaving inside Tat’s, where there are usually about two sandwich-scarfing cops for every plainclothes customer.
