Lots of South Florida delis tout themselves as "New York-style," but then they lack the basics: overstuffed sandwiches, a three-hour early-bird special (in this case, 3 to 6 p.m.), and the stocking of the delicacy meat called, quite simply, "cow tongue," which the uninitiated cringe at and the connoisseurs relish. 3G's has all of that and more. Whether cow tongue, pastrami, or corned beef, the sandwiches are sandwiches in name only -- more like pounds of thinly sliced meat with a piece of rye lilting on top for good measure.
