Walter's Hot Dogs has been in Mamaroneck, New York since 1919 serving up their exclusive blend of beef, pork, and veal dogs along with signature mustard.. a blend of mustard seeds, relish, and spices. Served out of a Chinese Pagoda looking building with a copper roof.
I'm glad they sell stuff online now.. you can get their mustard from their website (as well as shirts and other stuff) and their hot dogs from Gold Belly. I don't quite know how to write a review on mustard, but it is some darn good mustard. The hot dogs are fantastic. Split down the middle so it get more of that meat surface to get grilled. I'd order like 30 hot dogs at a time, because some would get eaten on the ride home, and the rest would be good for a few days in the fridge since it was a long drive from New Jersey.
I will say that the mustard and hot dogs rank up there are some of my all-time favorites.
