I've eaten my share but fewer as the years go by.
I've never seen a Subway sandwich with anywhere close to the amount of meat they show in their ads. I bet the sandwich in that picture has more corned beef than you would find on 6-8 actual Reubens at any given Subway.
Too many other good sandwich chains now i.e. Firehouse, Which Wich, Potbelly's.
Now I only eat at Subway out of desperation
