Star sightings: Warren G, Chance the Rapper, Patrick Kane,

SEEN ON THE SCENE: While in town, hip-hop artist and producer Warren G stopped by Public House for a Sunday brunch with a large posse of pals — taking the time to graciously pose for photos with fans standing nearby. … Keeping it very sober (while the season is still in high gear!), the Hawks’ Patrick Kane and (separately) Andrew Shaw chowed down on juicy steaks — but only drank water — at STK Chicago, where Chance the Rapper and a group of friends were also seen recently. Ditto for the Hawks’ Andrew Ladd and Duncan Keith. … Speaking of the NHL, among the recent sightings at Del Frisco’s on Oak Street were the Hawks’ Artemi Panarin and Artem Anisimov, joined by the Detroit Red Wings’ Pavel Datsyuk and Alexey Marchenko — with Russian clearly the language of choice.
