I carry the basics, nuts, bars of choccy, some dried fruit, a few wraps and some spreading cheese to get me though the day, I then eat out in the evening. If I have to wild camp and nowhere near a pub or restaurant I just 'make do' food wise and sip brandy or similar from my hip flask!
As for the top of mountains, or other nice locations, I will often carry a container of Ambrosia Rice pudding or custard and eat the lot whilst gazing out on some great view. Wicked!
