One of the reasons I hate the question ‘What is your favourite restaurant?’ (and there are many) is because you never know the weight that people personally assign to food, service and ambience. If the planets are aligned and the gods have chosen to smile on you you may get all three, but it’s rare.
For me food wins, followed by service and ambience. If the food is exceptional, I can make allowances for the other two. If the food is merely good, the ambience and service are pretty important. If the food is bad, nothing makes up for it; not the best, most professional service nor the most amazing fit out. However, I think good service makes you disposed to judge more kindly. My personal ratio if out of 50 would be Food /25 Service /10 Ambience 8/ (and edited to add, after it was pointed out I’d missed it out.. ) Wine /7. However, if the food was really good, the importance of wine would go up and ambience would drop right back!
So, what is the most important aspect for you, dear readers? Can you eat in canteen like surrounds if the food is good? Or is the service and ambience as much of the eating out experience as the food?
