Though it succeeds as a welcome addition to a Jäger-fueled stretch of Murray Hill, Cask’s offerings are mostly amateur. The name refers to its two rotating cask beers (unpasteurized, hand-pumped ales), which are worth investigating—we enjoyed a malty Defiant porter. But the rest of the largely domestic lineup is humdrum. Only a few options—like Ruedrich’s Red Seal Ale—deviated from the usual beer-bar staples (Blue Point Lager, Ommegang Hennepin). If you’re in the neighborhood and looking for a respite from fratland, you can’t go wrong by sticking to the casks and the menu’s few highlights, like the black-truffle mac and cheese.
