Philadelphia Bar & Restaurant, the latest entrant into the city’s thriving gastropub scene, is introducing a new limited-run prix fixe dinner on Sunday night. Undoubtedly, it will be one of the best deals going in Old City. PBR chef Jordan “Red” Sauter’s entire menu is available as part of the $27 three-courses-and-a-beer special. It will be offered Sundays through Thursdays until November 11, and includes a choice of appetizer, entrée, dessert and a pint of one of the bar’s two dozen craft brews. Finally there’s a reason — one that’s more affordable than Amada and Buddakan — to return to Old City.
