I went to the Centurion BK yesterday afternoon. I had the Big King XXL and a small chips. I went at 17:00 and I only had one person in front of me, and walked out with my food about 3 minutes later.
Verdict: The Burger was OK, better that what I remember McD (I last ate McD about 4 years ago) and on a par with a Steers burger, I would probably not buy another one in a hurry, but to put it in perspective - I'm not fond of takeaway food. However nothing beats a burger from Burger Bar or one that I make at home.
