KISS performed a low-key, un-masked, un-costumed set at the grand opening of their restaurant Rock & Brews in Torrance, CA last week.

Although Eric Singer was missing, Gene Simmons, Paul Stanley and Tommy Thayer still delivered 20 minutes of KISS hits including “Rock and Roll All Night,” “Lick It Up,” and “Hotter Than Hell.”

Simmons and Stanley own the Rock & Brews franchise, which also has locations in El Segundo, CA and Los Cabos, Mexico.  Reportedly, their plan is to open 100 locations in the next five years.
