Honestly OP, the "two raviolis and lettuce" option really sucks for a wedding. You and your bride will not be relaxed enough to enjoy it, and most guests will probably not very care much for it.

I'm not OP, but I too was indeed underwhelmed by Asimov. I genuinely thought I would enjoy it because I mostly read classic Sci Fi, and a ton of non-fiction, so from what I've read about Foundation, it seemed a good fit for me. But I found it badly written and a slog to read. I wanted to like it, but I couldn't.

>they are known to occasionally explode for no apparent reason

Seems like a pretty big flaw for a large-sized piece of equipment that's meant to be used by naked people.
