Is she only joking about getting together?

My friend and I went to a restaurant and all the booths were taken or dirty, so we just sat at one and got moved to a small table with just two close chairs instead. She joked about it being romantic and responded well to my Lady and the Tramp jokes. Although she still wanted to move back to a booth.
Later, while discussing my failed love life, she joked about us getting together. Is it possible that she was flirting? I noticed that she was twirling her hair a lot while we spoke if that means anything.
