Many good points, but I'd like to nitpick a bit:

> Singapore has way better clubs than SF or LA. If you want to party hard until late at night it's got plenty of options. Vs SF/LA where there's a 2am curfew your options effectively end at 1:30am.

> Try getting food in LA/SF after 11. Your options becoming Dennys and that's about it.

In LA, go to K-Town (Korea Town). Many good restaurants, lounges, and karaoke places stay open all night long. The party doesn't stop at 2AM.
