Seed-Oil-Free Restaurants
in Cambridge

Catalyst Restaurant is a New American fine-dining spot in Cambridge run by Chef-Owner William Kovel, who emphasizes locally-sourced ingredients from his farm-to-table philosophy. Their dinner menu explicitly features butter and olive oil in many dishes—including brown butter in soups, herb butter on steaks, and olive oil on appetizers. However, they do serve fried sides like French fries and garden bean tempura, and the specific oil used for frying is not documented online. We recommend asking the restaurant directly about their fryer oil when you call or visit.

Roxy's Arcade is a cocktail bar and arcade venue in Cambridge. Their Instagram and social posts feature butter-forward dishes — brown butter in cocktails, house-made bread with butter, and apple cinnamon butter on biscuits. While we don't have a complete menu review, the repeated emphasis on butter preparation suggests they prioritize quality fats. We recommend confirming their fryer oils and sauce base if they serve fried foods.

The Black Sheep Lounge & Bar is a Portuguese and Mediterranean small-plates restaurant in Cambridge with explicit menu evidence of butter and extra virgin olive oil use. The menu highlights butter-griddled lobster rolls, butter-based shrimp dishes, wood-fired flatbread with extra virgin olive oil, and roasted preparations. However, the menu does not specify cooking methods or oils for all items (fried duck wings, croquettes, fries), so clarification on fryer oil and sauces would strengthen confidence. Their focus on Mediterranean cuisine and named clean fats on key items is encouraging.

The Longfellow Bar's menu explicitly mentions "tallow fried peanuts" in their Fried Brussels Sprouts dish, which confirms they use beef tallow for at least some frying. However, the fryer oil for other fried items (fried chicken sandwich, shishito peppers, fries) is not specified on the menu. Chef Michael Scelfo runs an upscale, ingredient-focused restaurant with a "forward-thinking approach," which suggests quality ingredient sourcing, but you should contact the restaurant directly to confirm whether ALL fried items use tallow or if some may use seed oils.

The Painted Burro is a neighborhood Mexican kitchen with a farm-to-table ethos and four Greater Boston locations. Their house-made El Nacho Chips are explicitly fried in 100% avocado oil—a strong signal of clean cooking values. However, this evidence is from their branded chip product, not yet confirmed for the full restaurant kitchen. We recommend asking the team at Harvard Square about cooking oils used for tacos, enchiladas, and other fried items to verify the practice extends across the menu.

Umami Omakase is a high-end omakase restaurant specializing in sushi and Japanese fine dining. Social media content references signature dishes prepared with butter (miso butter halibut, brown butter cod hand roll, lobster and uni butter). Omakase restaurants typically prepare raw fish and high-heat seared items that don't require industrial fryers. No seed oil use was mentioned or implied. Confirmation of their complete cooking oil philosophy would require direct contact with the chef.

Veggie Galaxy is a fully vegan diner restaurant in Cambridge, MA that specializes in plant-based comfort food. Multiple third-party social mentions reference butter use (including in sauces and banana butter), which suggests the kitchen uses clean fats. The official website emphasizes "made from scratch" preparation of every dish. However, we could not find explicit confirmation from the restaurant's own official channels about all cooking oils used (particularly for fryer operations, if any). When you visit or call, consider asking specifically about cooking oils used for pan-frying, sautéing, and any fried items.

Zuzu's Petals is a wine bar in Cambridge that specializes in dishes like zucchini flowers and seasonal preparations. Their Instagram features a chef interview mentioning butter, and associated content references olive oil as a cooking ingredient. These are positive signals for clean fat use, though we haven't confirmed their full cooking method or fryer operations. Ask about their oil sources and high-heat cooking methods when you visit.

Dig Inn positions itself as a farm-to-table restaurant with scratch-made bowls and seasonal ingredients. However, third-party analysis has identified the use of vegetable oil (a seed oil category) in multiple dishes alongside some olive oil applications. The restaurant's own website does not explicitly disclose which oils they cook with. We recommend asking Dig Inn directly about their cooking oils when you visit or call, especially regarding their charred preparations and any fried or sautéed items.

Hot Chix Boston is a chicken and fried food restaurant that specializes in Nashville-style fried chicken sandwiches and fried items. The menu shows extensive deep-fried offerings (fried chicken, fried shrimp, waffle fries), which typically require commercial fryer oils. No information about their cooking fats is available on their Yelp, TripAdvisor, or any accessible web content. We recommend contacting them directly at contact@hotchixboston.com or calling 617-945-1980 to ask specifically what oil they use in their fryers.

Nine Tastes is a Thai restaurant with deep-fried items (crispy chicken, French fries) prominently featured on the menu, but they do not publicly disclose their cooking fats. Thai cuisine often relies on high-heat cooking and frying. Without explicit evidence of clean fats (butter, tallow, coconut oil), a Thai restaurant operating a fryer typically uses commodity seed oils. We recommend contacting them directly at (617) 547-6666 or via their website to ask specifically what oil they use for frying.
