Do u feel any difference in Mc Donald's coke any normal one????

no i dont find both cokes to be different

Its the ice they use at McDonalds and they might be mixing it diffrently like more syrup and less water, but yeah mcdonalds coke does taste better than a regular coke...

It could be like Coke at all other restaurants and fast food places. Because it comes from a soda fountain and is not bottled or canned it will have a different flavor because you are drinking water from the tape, carbonated on the spot by the machine, and then mixed with the syrup that gives Coke its flavor and color. That is totally different from driking something that has been bottled under pressure weeks or months earlier.
