Believed the hype, and went across town. Waited in a long line. Ordered. Paid.
I don't know what I was expecting, but it wasn't an upscale White Castle burger on cheap bread. Don't get me wrong -- I liked the burger just fine, and it was obvious a lot of love went into it, but after hearing, forever, that this was the best burger I was ever going to have, I was disappointed with what my visit yielded. It's billed as the best burger in the city when in reality, it's not even the best burger in the neighbourhood.
Still, you should go. It's an experience.
