Don Liberty, owner of the Bull Pen Pub & Grill (20011 International Blvd. in SeaTac), cut an ad in support of SeaTac’s $15 an hour minimum wage initiative, and I’ve been told he’s been catching some heat for it. So if you want to show your support, the Bull Pen has karaoke seven nights a week, darts, booze, stuff like that. Just sayin’.
