I added them to the NJ Hot Dog Sellers Map. Wrote them an email and they replied:

"Thanks for adding us to your list! We appreciate it.

We take your point but we think that people are willing to pay more for higher quality.

Our dogs are made specifically for us using top quality meat and we use fresh ingredients prepared daily for our toppings. Our prices are actually on par and slightly lower than comparable gourmet hot dogs establishments around the country. Our 20 year record in Princeton has given us confidence that we deliver quality for a reasonable price. Our food margins are industry standard.

Our wildly successful food truck (which has a higher price point) is indicative of our quality.

Regardless thank you for adding us."

So I wrote back:

"Alright. Well written. Everyone says their dogs are specially made for them. But not usually true. That should be one of your main advertising points. Others have commented on the high prices as well.

You've talked me into trying your place. I mean the dogs do look tasty.

Well good luck regardless."

If their truck is so successful then how come I never heard of them? I regularly search for hot dogs and I visit Princeton often.
