We tried the location at Sahara Mall in Riyadh and I will make it quick and simple:
Price is outrageous, especially for a food court location. The cheapest burger goes for SAR 25 all the way up to 35, no fries or drinks included!!!!! The size of the burger is big but no real flavor or taste, even with the toppings. One of the reviews I read called it "very bland" and I could not agree more. There were chunks of grizzle in my sandwich. My son wanted mustard on his burger so they charged us 2 riyals (compare that to any other similar restaurant anywhere which would have been for free). It turned out to be spicy Dijon mustard. Who serves a kid spicy mustard??? When we asked about the mustard, they said spicy mustard was the only one they had but they were kind enough to make another one for him for free. There are no refills for the drinks. The fries are good. We paid SAR 158 for our meals (2 adults+2 children), a rip off for a bland, over-sized chunk of ground meet.
