Katz's, Gray's, F&B...all awesome dogs. I had a dog last week that surpassed my wildest expectations. The only problem is that it is mail order and you have to cook it yourself. The meat was most flavorful, butm best of all, the casing was perfect! Just the right about of resiliency. I got them from a place called Usingers, a Wisconsin-based German meat maker. I have purchased Braunschweiger liver sausage there for years and then I tried the "Wieners". Unreal. If you go to the web site, don't get confused with all the offerings. Make sure you try the wieners with natural casing. I'm sure the frankfurters are good too, but I can only attest to the wieners (not the beef wieners, not the veal wieners, simple the wieners!). The web site is www.usingers.com. P.S. They also have great brats!
