Pub & Kitchen will treat guests to complimentary Churchill sliders, downsized versions of its LaFrieda and bone marrow masterpiece, today from 4 to 6 p.m. to celebrate that the burger has made it to the final round of Phillymag’s Best of Philly Burger Bracket. It squares off against the Whiskey King burger Iron Chef Garces serves at Village Whiskey. In addition to the free sliders, the P&K; crew is also offering specially priced oysters and their Sixpoint Middleton Ale.
