Had a chance to enjoy Frank at the Scottsdale Food Truck Caravan twice - totally awesome both times. The lobster mac n cheese dog of course was amazing. The other dog I tried was the nightly special - I forgot what it was called but it had tomato jam, arugula, nuts, and pancetta on it - it was so freakin' good that I still have cravings for it... Maybe it was called the Wayne Newton? I don't know, but it was awesome and went really well with the homemade chips. Highly recommend you try this place ASAP!!!
