You should eat in a buzzing 17th-century market, especially when it’s the oldest covered food market in Paris. This Marais favorite is known for its stalls of produce, fish, cheese, and casual countertop-style stands representing international cuisines. Midday, you’ll rub elbows with locals on their lunch break as they line up at Chez Alain for customizable sandwiches as big as their heads, and throw back tagines from the Moroccan deli or cool soba noodles with vegetable tempura from Chez Takeo. For a longer, sit-down meal (that carries a higher price tag), arrive at the start of lunch to snag a stool at Les Enfants du Marché, a seafood and natural wine bar with a party vibe and enough whole fresh fish to make you feel like you’re beachside.
