I think all the hype has set too high an expectation for this place. I've been to the Yonge and beach locations. And both times I left confused by all the 5 star reviews. It's good, but I wouldn't say it's the best.
It's a great burger, I don't mind spending $11+ tax if it's good. I got something off the normal menu, but some people have written it as a secret menu item. It was a double cheeseburger, with grilled cheese sandwiches as buns. The meat was good, and the grilled cheese buns were amazing. However, the food was VERY greasy, my wrapper stuck to the table. I was also disappointed by the use of processed cheese. With 3 to 4 slices of cheese in my burger, I would've liked something of better quality. That took down a star.
I got a combo, with fries and a drink. The fries were very good. I don't know how often I want to spend the extra money on fries but if you're hungry, I would recommend it.
The place is tiny, and I was glad not to wait in line for it. But usually when you go there's going to be lines. Passed by it for months before I went there, and I have never seen it (until today) without lines.
