Famous faces spotted: Johnny Galecki, Jimmy Butler, Billy Corgan

SEEN ON THE SCENE: “The Big Bang Theory” star Johnny Galecki, who grew up in Oak Park, was back in town and spied supping at Rockit Bar & Grill and Bottlefork. … Also spotted by fans at Rockit was actor Joe Sikora (“Power”) and ex-Blackhawk (and current member of the Calgary Flames) Brandon Bollig. … After I ran into Jimmy Butler in London (where he was hanging out with good pal Mark Wahlberg, who was doing press for his upcoming “Ted 2” flick), the Bulls star flew home, where he headed to Prime & Provisions for a dinner — in reverse order. After starting with apple pie, Butler moved on to Caesar salad, and then the non-red meat-eater chowed down on some fried chicken and salmon. … Billy Corgan was among those quietly dining at Nellcote on Randolph Street over the weekend. … Yes, that was “Chicago Fire” star Joe Minoso sighted at RM Champagne Salon. … Imagine Dragons guitarist Wayne Sermon was seen celebrating his birthday at the Pump Room at Public Chicago, where (sadly) the famed Booth One telephone is still missing. … Before prepping for their Monday night Stanley Cup broadcast duties, ESPN’s Barry Melrose and Steve Levy dined Sunday night at Tortoise Club on State. … Meanwhile, elsewhere in River North, the Hawks’ Andrew Shaw was getting his steakery fix at Chicago Cut. … Former Major League pitcher Randy Johnson and Rush music man Geddy Lee were spotted at Spiaggia. … Hockey fan and music star Tom Morello of Rage Against the Machine checked out the new For the Win super-arcade in the AMC River East movie complex on East Illinois — obviously thinking Stanley Cup as he played both air hockey and Blackhawks-themed “bubble” hockey with his kids. … “Empire” creator Lee Daniels — back in town prepping for the second season of the hit Fox series — stopped by the cold-pressed juice bar Owen + Alchemy in Logan Square.
