In the middle of the Marais in Paris there is a Jewish quarter with a complicated 800 year history. These days it's mostly home to recent Jewish immigrants from the Middle East. It's a great neighbourhood to find a quick cheap lunch, something different from the usual French food. Felafel, schwarma, bagels, etc.
One of the best known places there is Chez Marianne. It's an overgrown traiteur; their primary business is selling premade salads, deli foods, etc. But over time it's evolved into a restaurant with table service and is now quite popular at lunch. My assortment plate had hummus, tzatziki, roasted peppers in oil, feta, and a meatball. And some excellent pita bread. Way too much food, but good.
