Sabrett's Natural Casing Hot Dogs
That's a nice site. That gave me the idea to look for this site:
You can buy Nathan's (natural casings) dogs here, albeit at inflated prices. I would probably call them to find out if they have either local or wholesale distribution, particularly if you are looking for bulk pricing.
By the way, does anyone remember Nathan's Chow Mein sandwiches? Or their fabulous Cherrystone clams? Can you still get them?
As a native Brooklynite I well remember 3 am mid-week dead of winter treks to Nathan's in Coney Island for Chow Mein sandwiches. The cars were always triple parked too. How's about the fried shrimp sandwiches? I also remember the personality quirks of their long term employees, real characters. I drove by a few years ago in the day and the original place is still there but seems to have fallen off.
