Calling and asking plus double checking with chef is your best option. Vegetable oil most often. Allergy issues with Peanuts and all.
The safest thing to do is call and ask better safe than sorry
Call to ask...
You are most definitely being guided in the right direction. Just call, surely not worth the risk.
I definitely would ask. A call and mentioning a food allergy when eating out would always be recommended anywhere you dine.
Most places cook with vegetable oil. But your best bet would be to call up there and find out for sure.
