Have you seen this tradition in your local French bistrot (or bistro--I don't know the difference)?
Here in Chicago at Bistrot Zinc patrons who have a drink at the bar while waiting for their guest to arrive may enjoy a fresh hardboiled egg, gratis, on the house, free!. Just crack it on the zinc bar--the bartender will bring you a small plate and some salt and pepper--it's a perfect "tie-me-over" until your table is ready. They also have notoriously delicious, freshly made waffle potato chips--no body can eat just one.
I love the carousel wire holder for the eggs, how about you?
Okay, here's the real reason I love it at Zinc:
One perfect Norman Invasion.
