The actual diner is an old Worcester Dining Car Diner. It's history is featured in the book Classic Diners of Massachusetts.
They even have a Facebook page.
Tex Barry's is owned by Arthur Bombardier. He took the joint over from his mother back in 1985- she bought it from one of the original franchisees back in 1979. Tex Barry's was once a burgeoning hot dog franchise in the Southeastern Massachusetts area, but only two remain- the one in Attleboro and another in Taunton, MA.
Tex Barry's has- like any "real" Coney Island Joint- it's own secret recipe for their sauce. Like any self respecting Coney Island Dog man, he wasn't sharing the recipe. Arthur serves em up with the works: a grilled Kayem frank with Coney sauce, onions and mustard on a steamed roll. Old school, authentic, iconic, and DELICIOUS.
I ordered up one with the works (I eventually downed three)...
...and some fries.
Little Miss got her standard half plain/half mustard.
