Mayonaise, onions, beef stew, peanut butter, tartar sauce, pickles, cocktail saus, andaloes, barbeque sauce, bicky sauce, joppie sauce, Hawaii sauce, Brazilian sauce, tomagrec, chilli, curry, Mammoet, Samurai and some do a combination of several.

The list of options to put on your fries here is long.
