The pattern for once a week group appeared to be reversed. Percentages tended to fluctuate around 30% in once a week group with the highest level of people in both 2003 and 2006. Meanwhile, numbers in several times a week group saw a similar trend. It had slightly fewer people in 2003 and 2013, with a high of in 2006.

Both figures for people who ate every day and never ate decreased by the same small amount of about one percent, while in 2013, the figures showed no change for both groups. However, for people who ate a few times a year, there was a marginally larger increment of 2% from 2003 to 2006, and then the figure stayed unchanged until 2013.
To sum up, it is clear that restaurants enjoyed the greatest popularity in once a week and once or twice a month groups while they were visited the least frequently in every day and never groups.
