The choice is yours.
I usually tell my guests to pass, but it's up to you. I mean they are regulated but I'm not going there. I'm more interested in those that work the stands and those that buy from them... I will remain an observer. Before I moved to NYC my boss threw me a great party to send me on my way with cosmos, a hot dog stand and even burning pretzel salt to create an ambience of the city right there in San Fran. I'll never forget asking why and Bonnie saying, "Once you get there, you'll know". Twelve years later I've still only had one.
