Brothers Ryan and Eric Berley do the old-school soda-fountain theme right — with antique fixtures, an authentic menu of creams and fizzes, and a dedication to the best ingredients. Taste their success in a milkshake so good that you have to remember to breathe between sips. The consistency is smooth but not soupy, with the not-too-sweet homemade ice-cream flavor coming through, allowing for (one bellyache later) maximum intake. A long spoon lets you finish every last drop.
