We were impressed by those one-cent ice cream cones last week, but this might be an even juicier deal – Katz’s Delicatessen has not only cut the price of its massive corned beef and pastrami sandwiches to $10 each (if you’re one of the first 200 to order via GrubHub from noon till 10 p.m. today), but in an unprecedented move, they’re delivering to the East Village and points beyond. We’ve just placed our order via GrubHub’s Facebook promotion and will let you know how it goes. Update: Our pastrami sandwich arrived (with pickles!) at 2:10 p.m., just a little over half an hour after we ordered it. Heaven.
