• Cuisine: Artisanal European-style café & fry shop
• Best for: Peanut/nut-free dining, gluten-sensitive fries

A perennial favorite in the Old Port, Duckfat is famous for hand-cut Belgian fries twice-fried in rendered duck fat, craft paninis, and house-made milkshakes.

• Zero vegetable/nut oils for fries: Their signature fries are prepared exclusively in duck fat in dedicated fryers, making them safe from shared nut or soy cooking oils. (Note: Ask about the seasonal fry sauce ingredients.)
• Scratch-kitchen modifications: Because soups, salads, and dressings are made in-house, the kitchen staff can easily verify spice blends and modify ingredients for dairy, egg, or allium sensitivities.
• Pro tip: Duckfat is small and very popular; arrive early or use their waitlist system while exploring the Old Port shops.
