The two were photographed leaving El Compadre restaurant in Hollywood with Evans carrying leftovers, reported Ace Showbiz.
Evans, 33, wore a red shirt paired with grey pants with a black belt. The 'Captain America: The Winter Soldier' actor's hair was slicked back. He completed his look with a pair of sunglasses and brown shoes.
McKeon, 32, meanwhile, wore a black leather jacket over a dark grey tee, black skinny pants and black boots. She completed her look with a black bag.
The duo, who previously starred on 'Opposite Sex' together, are apparently just friends because McKeon is a married woman. She tied the knot with Brant Hively back in 2013. She was also seen wearing what appeared to be a wedding band on her left finger during the outing with Evans.
