The Las Vegas locations I've visited have veggie dogs on a stick while neither of the Hawaii locations do. *sigh* If I want to pretend to eat healthy dogs on a stick, I have to go to the mainland.
Anyway, all of the hot dog on a stick locations I've been to have had two things in common. The food is very consistent and served piping hot. And the service is always fast and very friendly.
If you're staying across the street at Sunset Station and just can't do another of their buffets, a hot dog on a stick with a freshly squeezed lemonade makes a great and light alternative.
