I have seen that in a few places back east and in Pittsburgh as well. I've seen "reuben w/ choice of corned beef or pastrami" a lot too. I've actually tried it and it's not too bad, but it's a long way from a reuben - and I like pastrami. Always reminds me of the Mitch Hedberg joke about turkey-based substitutes for ham/bologna/pastrami - "Man, be yourself! You've got your own thing goin'! People like you!"
