Walking into Hook Burger in Burbank, I had the odd suspicion that I had walked into some grown-up version of Habit Burger. It wasn’t until I got home and looked up the place for this review that I realized just how right I was. Hook Burger is quite literally a grown-up Habit Burger, started by the same guys, but featuring more of a fast-casual concept that also includes booze. And the use of the word “hook” is a clear reference to hookers, which are totally a grown-up thing as well.
