As much as people like to deny it, food presentation is as important as any other aspect of eating, especially when dining out.
I worked in (mostly full service) restaurants for years, and it was my experience that I could serve a mediocre meal, beautifully presented and get rave reviews.
Try to serve something something supremely delicious that is odd, unusual or ugly looking and the vast majority of people will either refuse to try it, or will turn their nose up at the first tiny taste.
The average diner wants an identifiable piece of meat, a starch (potato/pasta), a contrasting vegetable and some sort of sauce or gravy.
If there isn’t some sort of color on a plate, the diner might be satisfied, but they won’t rave. No matter how nicely seasoned and how delicately cooked, if you serve a sauteed pork chop with mashed potatoes, milk gravy and cauliflower with white cheese sauce you’re not going to get better than high-average (bland) feedback.
A handful of chopped pimentos in the green beans, while adding little flavor, can turn the tide on a dinner plate from good to great.
