Every year, 5 of my friends and I embark on a "hot dog safari". We select five "great" hot dog places, go to each one and sample the wares. This year we've selected the East Bay but only know of Caspars, can anyone out there help us out, we're looking for some good recommendations. We hire a limo for this kooky event because we also drink bloody mary's enroute, so parking won't be a problem. Last year was a blast in the San Jose/Silicon Valley area but we're sure there's more in the East Bay. Thanks in advance for your help. Just remember, no tofu, no vegan and no chicken or turkey dogs. We like to call ourselves "purists".
