Is there such a thing in LA?
When we folks here talk about hole-in-the-wall finds or discoveries, they're usually ethnic dives of Asian (e.g. Chinese, Korean, SE Asian), Mexican or Central American persuasion.
Or they even might be the good ol' American hole-in-the-wall joint. Like that (formerly) undiscovered hot dog stand, or a BBQ shack serving their secret sauce on the tri-tip sandwiches.
But, is there a FRENCH hole-in-the-wall joint out there? A sort of hidden, no-frills nook that offers up well-made French onion soup or a properly prepared salad niçoise served with a nice crusty bread.
