Channing Tatum wasn’t on the menu, but when the “White House Down” actor walked into Prime 112 Steakhouse in Miami on Sunday night, one staffer quipped, “He’s the finest piece of meat in the restaurant right now.” Tatum dined at Prime with nine friends, and as soon as he entered, a source tells us, “All eyes were glued on him. Every woman in the restaurant dropped their forks and stopped eating to stare at him before he sat. Tatum flashed a big smile and welcomed the attention.” Tatum, who in May welcomed a daughter, Everly, with his wife, Jenna Dewan-Tatum, indulged in a South Beach feast of seafood platters, steak, chicken and waffles.
