Terrible I really truly do not understand how this is remotely close to best burger.
I had the bacon double cheeseburger. It was absolutely drenched in oil, tasted like the bun was dripping in butter, really oily fatty mince, plastic cheese. I am going to regret eating this later I am sure. My gfs California burger was even soaking wet bun. Revolting. Shake was good that's about it, but nothing special.
Oh and it's an absolute rip off.
