Only McDonald's Honey Mustard goes well with fries. BK Honey Mjustard is good with Onion Rings. I like ketchup, I have all sorts of ketchups from American ones to Russian and even Polish or Czech, I don't know. Ketchup goes really well with fried stuff.
Later on I will go to Chinese place and order plain Lo Mein and will fry some stuff at home and will mix it with Lo Mein, because I dont wanna pay more dollars for fancy Lo Mein because I can cut the cost with my own additives.
