Fun curry fact: In the Netherlands and Belgium we often eat curry with fries. Mayo, Curry and raw onions a common topping. Called "speciaal" [1]. Though in other parts, they will use Tomatoketchup (mayo and raw onions) rather than curry.
If you ever visit the netherlands, make sure you get one of these. Or better even: frietje oorlog (fries with war).
