Skating legends Kristi Yamaguchi and Brian Boitano, in town for the US Figure Skating Championships, were spotted closing out City Bar at the Westin Waterfront on Saturday night.

Champ Kind of “Anchorman,’’ a.k.a. comedian David Koechner, dined at Abby Lane after his Friday show at the Wilbur. He had chowder and posed with busser Ruben Orozco.
