Weighing in at slightly less than a pound, the Reuben ($6.99) at Kahn's Deli is a delicious way to exercise jaw muscles. It's a jungle of pungent sauerkraut, piles of corned beef and a thick layer of melted Swiss cheese that makes one wonder if any human can open their mouth wide enough to get a traditional bite. The Russian dressing is made fresh every morning using an old family recipe, and it's not spread on so thickly that the freshly baked rye bread gets soggy. (Unused bread is donated to a church to feed the hungry at the end of each day, so customers never get day-old bread.) Owner Mike Kahn got the recipe for the Russian dressing and the rye bread from his father, Alfred Kahn, the namesake of Alfred's Deli, which closed in 1994 after Alfred's death. They are continuing the family tradition, serving the same hefty, tasty and wonderfully messy Reuben.
