With a five-station mixer constantly making shakes, malts and sundaes, the counter staffers at Yale Street Grill have their hands full. It is unknown whether they've been making shakes since 1923, when they opened, but the mixer sure looks the age. They start out with two or three generous scoops of Blue Bell ice cream, a good amount of milk and, in the case of the Oreo version, enough crushed cookie pieces to make it impossible to suck through a straw, no matter how big a sucker you may be. A spoon is definitely required. Classic flavors -- vanilla, strawberry, banana and chocolate -- are all available.
