You know the drill. Semi-fatty discs of medium-rare beef stewed with chicken broth, pork bits and glass noodles in a steaming bowl as big as your head. You’re eating pho — the incomparable Vietnamese soup that’ll make you wonder aloud why those cartoon kids on the Campbell’s cans look so friggin’ happy. For real bite, throw in a few of the fresh jalapenos that come with the pho at Van Loc. Soup is good food, to be sure. Adventurous eaters choose to add tripe.
