I’m not sure what brand they use but it is grilled split down the middle. The burgers are fresh, never frozen which says alot. I spoke with the franchisee, he actually came around to talk to people but for some reason I totally forgot to ask about the brand. I have eaten at Rosco’s and I do enjoy Thumanns but I was neither impressed with the dog or the prices. A Big Dog w/ everything on it was almost $6.00 for the dog alone!! The fries were gritty like they were never washed and the soda was way over priced and I was charged for a refill…It should cost the owner around .12 for cup, syrup, seltzer, lid and straw and he charged close to $1.50 for a medium..which is ok but then to charge for a refill is rediculous…I won’t return because 1 reason GREED!! I understand that a business person needs to make a profit but to me this was pure greed. I have never been to a hot dog joint that was this expensive! And I was there in the summer and it was 92 degrees inside (according to the thermometer on the wall behind the counter), the employees said the owner won’t fix the a/c or upgrade it…do they charge extra for the sweat that was dripping off the employees into the food?? As for a chain on roadfood..what do we consider a chain?? Many hot dog places venture out and open other stores, do we take them off as soon as they open a second store? When Doogies opened a second did it come off? How about Pinks expanding to Vegas does it come off Roadfood cuz its now a chain?? Just wondering? I hope we can keep on discussing great roadfood places regardless if they are 1 or 50.
