Agree that it is serviceable and perfectly drinkable coffee.
In marked contrast to Starbucks, where I have never had a good coffee, in McDonalds, - now that you mention it - I have never actually had a bad, or awful, or execrable coffee (all of which I have had in Starbucks, whose whole raison d'être is supposed to be coffee) in McDonalds; actually, their coffee has been consistently perfectly adequate and more than drinkable.
Fair comment, and credit where it is due.
And here, I will throw in another positive comment on their restrooms; they are always clean, and a very welcome space and place in some countries where hygiene and the whole process of infrastructural development can be - shall we say - somewhat tardy, or belated.
