 Many local Subway shops still have Old Bay for use on sandwiches.Old Bay is also occasionally used around the Chesapeake Bay region as an ingredient in Bloody Marys, and even in places as far south as The Breakers Hotel in Palm Beach, Florida.Some bars in the Baltimore region also often sell what is known as a 'Crabby Bo', which is National Bohemian beer where the lip of the glass or mug that is being used is moistened and dipped into a container of Old Bay seasoning.
