Welcome to NC!! Thank God, another Vienna hot dog place! I’m sorry you’re only open M-F and for lunch as I live a couple hours away.
I’m wondering if the competitor your referring to is Matt’s? I’ve tried there’s and found it to be just ok. I also found this place, but have not tried it yet, nor do I know if it’s still open:
Well, good luck w/you hot dog stand!! Every new one is important!!
