Mc chicken sauce and fries
McD's Sweet & Sour sauce and their fries FTW! Even if I order a burger, I always get an S&S sauce to dip the fries into. now that some McD's have started charging for the sauce (if you're not buying nuggets), I'll "forget" until they put the food on the try before I suddenly "remember" to ask for one.
Wait, or are you talking about the "white sauce" that they put on the McChicken burger? Because that's nothing but regular mayonnaise.
Do you mean the McDonald Chicken McNuggets with French fries Meal? Or something else?
I used to love chicken mcnuggets, but I haven't had them for a long awhile (no apparent reason). I guess I have to try them -- now that my Fish McBites are gone. :(
