The pug-loving folks at Central Square’s PAGU are celebrating the restaurant’s one year anniversary on Thursday, January 25th and you’re invited to the party. Chef-owner Tracy Chang is teaming up with friend and fellow chef Kevin O’Donnell of SRV in the South End for snacks, Lamplighter beer and a possible pass of the porrón. The birthday bash runs from 8:00 through 11:00pm. You don’t have to bring a present, just get your tickets here for $25 each (including tax and tip), and make your way to Mass Ave. for the birthday festivities.
