Though it was supposed to go through April, Umberto’s has retracted the buy-one-get-one-for-half-off special that it trumpeted on its windows for just a few days. “It wasn’t working out for us,” an employee said. Okay, fine, but you know who is still doing this deal? Charley O’s in Times Square, baby! They’ve got a guy giving out coupons at the door and an annoying loudspeaker trumpeting their “Unbelieveable Happy Hour” and $19.95 “price fix” menu. Finally, you can afford to slum it!
