What's the difference between "slap-up meal" and "gourmet meal"? [closed]

The following quote comes from a collocation book for ESL purposes. I can see it's trying to teach us about the usage of different expressions to describe different kinds of meals.

"Whether you want a slap-up meal, a gourmet meal or just tasty, home-cooked food, there’s something for everyone in the Old Port restaurant area.

I'm interested in the difference between "slap-up meal" and "gourmet meal". My initial thought after doing some google search is this: A "slap-up meal" is an excellent meal which tends to be heavy and substantial. A "gourmet meal" is also an excellent meal, but usually calls to mind the delicate and exquisite type. Both are tasty of course!

You have understood the distinction pretty well.

Slap-up has the connotation of self-indulgence, plenty of food of the kind one really enjoys, possibly piled high on a table from which one helps oneself, presentation is not a major factor. Think succulent pies; think Spotted Dick and custard.

You might find this question interesting.

Gourmet is about fine-dining, exquisite presentation, a single carrot placed just-so, foams and gels, foraged herbs, interesting flavour combinations (snails and liquorice anyone?) 14 course tasting menus and a small mortgage to pay for it all.
