I visit the McCafe at the Duncraig store occasionally, and have found the coffee to be pleasant tasting, easy drinking and hot! The "baristas" have usually been quite disinterested, but are reasonably efficient and I'm usually out of there within 10 minutes or so.

Recently however, I needed something to eat in a hurry, so I lined up in the restaurant section to order a burger and fries. I'm not sure what was happening that particular day, but there were only a few people in front of me, yet I ended up waiting 15 minutes before I could even place an order! By the time I had my meal and McCafe coffees takeaway, I had been in the store for over 25 minutes. Anyway, the burger, fries and coffee were all hot that day, just the service was a tad lacklustre.

Overall - a standard "McDonald's" experience, but the service could have been a little cheerier, and a little less tardy.
