Taylor Swift celebrated with Travis Kelce Sunday night at his steakhouse, 1587 Prime ... and we're guessing he destroyed his filet just like the Chiefs annihilated the Raiders.
Travis and Taylor were filmed by a fan making their way through the K.C. joint that TK co-owns with Patrick Mahomes.
Prior to date night ... Taylor managed to avoid TV cams at Arrowhead. She was, however, filmed by a fan in her suite.
