The world has gotten better since the era when I first started flying for business, when a good airport dinner meant White Russians and warmed-over hotdogs.
The food isn't quite on a par with the main restaurant, but it'd still qualify as good restaurant food. A burger is a respectable upscale burger that I'd call pleasant yet unmemorable... but the fries! The fries! The fries are even more addictively amazing that Smashburger fries. Whoever was in the kitchen is the maestro of fries. Whoever's choosing their wine is also brilliant. Given usual mark-ups, my choice is probably pretty cheap in the bottle, and it had the dimensions of something much pricier.
The push from 4 stars to 5 was that I went here hoping that an airport might have servers familiar with the concept of "lone woman diner," so I'd get decent service. My server was wonderful: present without being obtrusive, helpful, and generally everything I could ask in a server. She got a 33% tip. That won't pay anybody's rent, but it's better than an empty table.
It's great living in the future.
