In-in-Out likes Mopars

Only onions you're gonna get at In-N-Out is on your burger - either raw or grilled.
In-N-Out markets burgers, fries, drinks, and shakes. That's it

Just curious. There's a Tastee In-N-Out in Iowa that has onion chips. Like onion rings but chunks instead. They are breaded and fried and delicious.
The restaurant must not be part of the chain. Mike
