Just okay. 3 significant flaws.
I fix a mean burger, and I'm picky about where I go to eat one, so I rarely try a new (to me) burger joint.
The 3 main flaws: 1. Red onion. Should be yellow. They are sweeter, have more flavor and are smoother (red onions are not smooth). 2. Beef was too lean. Should be no leaner than 85/15. Makes a burger too dry. 3. Funky pickles. Just use hamburger dills. The pickles here are weirdly spiced. Burgers are supposed to be simple and basic. No need for strange tasting pickles.
Whole wheat bun was outstanding.
The potato chips were very good.
Service was a little slow but about normal for an airport eatery.
The classic rock music was enjoyable in an era where most public music is repetitive and tasteless.
