This is the only Reuben I like. Table service is available but isn't always good so it might be better to just wait in line first. Across Ludlow and down a few doors is Pink Pony Cafe...It's an okay dinner place but a nice spot to take the wife for desert or coffee.
New Yorkers take cheesecake very, very seriously--if you want some of the best, go to Katz's! You'll also probably recognize it from a certain scene in "When Harry Met Sally."
