Call her and ask her out today, and if she remembers who the hell you are, I guarantee she'll say yes. Say you enjoyed talking with her last night, and would like to see her again.

By the way, you could have told her that the word unique, by definition, does not take qualifiers, such as "very" or "most", and there is no such word as "uniquest" as "unique" itself is a superlative, but why ruin the moment.

Good luck. It sounds as if she likes you.
