I had the Inferno. Incredible burger.
I love burgers. Let's get that out of the way because everyone else does a pun of sorts with this restaurant's name.
Apparently everyone had a terrible experience with this place except for me. I will admit that the price is a bit out of touch with reality - $6 for a 5 ounce burger is overpriced, to say the least. On the strip or in an amusement park, I would understand, but this place is overpriced for its value.
That being said, whether you put it in the category of Fast food or not: (Fuddrucker's, In-N-Out, 5 Guys, Smashburger, etc.) I will say this burger is incredible and contends as the champion of them all.
Their $6 Orange Delight shake was also overpriced, but it was "Pulp Fiction" good and I was wow'd to the core. I might return for the shake alone.
The service was very above par.
Short story: You get what you pay for, but in quality, not quantity.
