Investigation
4 seed oil-free restaurant listings that are out of date
By the Seed Oil Scout team · Published October 20, 2026 · Updated October 20, 2026
Are seed oil-free restaurant lists accurate?
Not always. Restaurants change cooking oils, and a list that isn't rechecked goes stale. We compared all 6,098 restaurants on Local Fats with Seed Oil Scout's 57,000+ diner reports and found restaurants listed as cooking with tallow or other traditional fats where recent reports, including staff answers and a written reply from one restaurant, show seed oils in use. Here are four, with the evidence and dates. Seed Oil Scout rates 44,000+ restaurants from diner reports that keep coming in, so ratings move when kitchens change.

Why listings go stale
Restaurants switch suppliers, change owners, add a cheaper fryer oil, or buy fries that arrive pre-fried in canola. A directory entry added once can keep saying "beef tallow" after the kitchen has moved on. Local Fats shows no listing or last-checked date on these entries.
How Seed Oil Scout keeps ratings current
- Diners ask staff what oil the fryer and the kitchen use, then report it in the app. As of October 2026 there are 57,000+ reports.
- Each restaurant's reports are reviewed together. Newer, more specific evidence, like a staff answer about the fryer oil or a written reply from the restaurant, outweighs older or vaguer reports.
- When a restaurant changes its oil, the next specific report changes its rating. A listing that was right in 2024 doesn't stay on the map as fact.
- Verified restaurants pledge their cooking oils. When the evidence contradicts a pledge, the verification is revoked.
