Crispy beef is what they call their signature patty. The default is two slices, but you can add or subtract. The USP is the patty is smashed and grilled til crispy at the edges. This American burger concept from Hong Kong (convoluted, I know) is also known for its fresh and premium ingredients. Overall, I'd say it's a simple but shiok burger, just missing the mark of a perfect burger. I loved the mess of the juices and the decent beefiness. I further loved the decor, which is a detailed impression of an American diner, including the jukebox.
