What oil does Mastro's Restaurants fry in?
Mastro's Restaurants cooks with Wagyu beef tallow (low PUFA) for the fryer, per their own dinner and lunch menus, which label the Potatoes & Fresh Vegetables section "Proudly frying with Wagyu Beef Tallow" (covers French-fried potatoes and other fried veg sides); steaks are broiled/grilled in-house, and Fried Calamari appears on the same menu but the tallow line isn't scoped explicitly to seafood, so treat calamari oil as unconfirmed..
The 5 cleanest things to order at Mastro's Restaurants
Learn this once: a salad with grilled protein and the dressing left off is nearly always the lowest seed oil order anywhere. So the list below sticks to real meals, salads included, never just a water.

| Oysters on the Half Shell | 0.0g |
| Shrimp Cocktail | 1.0g |
| Lobster Cocktail | 1.0g |
| Chilled Crab Cocktail | 1.0g |

Lower PUFA is cleaner. These are estimates from published nutrition data and disclosed oils; preparation varies by location.
Why the frying oil matters
Most fast-food chains fry in seed oils like soybean, canola, corn, or a blend of them, which are high in polyunsaturated fat (PUFA). A handful still use beef tallow or other stable fats, which are far lower in PUFA. The oil a kitchen fries in is the single biggest driver of how much seed oil ends up on your plate. See the full breakdown on the Mastro's Restaurants report card, or where it lands on the Seed Oil Index.
