tl;dr the burgers are average, but factoring in the price of the food i would strongly recommend eating somewhere else.
The roof location for the restaurant does add to the experience but that is single most positive comment i can give. The restaurant is not unlike a typical bar or diner that you'll see in the UK or US (it is burgers and wings after all), but be prepared to pay restaurant prices for your experience, a meal with a drink(they don't water and a drink costs 5$), side+dessert would set you back more than $40.
As a burger lover, i tried both the tyson burger (with peanut butter) and a classic cheeseburger. I have to say that the classic beef burger was actually terrible, it left me really disappointed, it is definitely needs revisiting (imo this is a cardinal sin for any burger place). The peanut butter on the burger didn't taste bad at all, itwas a pleasant touch, but besides that little bit of spontaneity, no further effort was made to make it a house special, so basically what i got was a burger with regular sauces i can find at home, with peanut butter on a very average bun.
Food taste was barely average.
