It's debatable whether these components can actually be segregated that way. In practice, no, every review system is plagued with reviews in the form of 'delicious food, lovely staff, but another table was too loud one star.'

I'm saying it's difficult if not impossible to disentangle these elements. The vibe, perhaps even the staffs' moods, will be in part a function of the diners. That, in turn, turns at least in part on the food. And vice versa--a place with a devout following that respects the kitchen staff will probably produce better food and ambiance, as both arise out of a sense of mutual respect.

You may not care about the food directly. But if your barmate in a fun outfit with a contagious laugh does, that's part of the vibe you're there to feed on. (I love food. But I've sometimes found myself winnowing down a list of restaurant options by the lighting.)
