Why does cheese as a dessert cost more?

[PH5121]

I am not a foodie so haven't ventured into this area of the forum, but know that there are some knowledgable folks about.

I don't have a sweet tooth, so if given the option of cheese as a dessert I will opt for it. My wife and I went to a local bistro type eatery at the weekend and had a meal, the sort of place where two courses are £20 and three courses are £25. I had the cheese/ fruit / chutney / combo for dessert at an additional cost of £3 or £4.

I am just curious to know why there is an extra cost for this, I have noticed in other eateries that the cheese based dessert option is often the most costly option.

I told you I wasn't a foodie!! I would normally use the phrase 'afters', as it comes after the main course!
