I often drove by the Korean-language 영빈관 sign on the door of Tokyo Japanese Steakhouse & Sushi Bar and only recently learned it closed. A 2006 Pittsburgh City-Paper review called it "a jewel box of authentic Korean and Japanese cuisine", and a July 2004 Post-Gazette review lists a few other places in the city that offered Korean barbeque:
Unfortunately, few joints offer Korean barbecue in Pittsburgh; Sushi Kim, Jimmy's Korean Grill at Jimmy Tsang's and Ginza are the noble few.Three of the four, including Young Bin Kwan, are now closed, and the fourth has sushi in the name. Bad news for the local Redditor looking for all-you-can-eat Korean BBQ places last week.
