Real Scenario below. Why would my new female coworker change her stance on something to match mine?

She said she liked someplace (1) over another place (2) but when she asked me, I honestly told her that I liked another place (2), and then she said, "then I like 2 too."

She obviously is showing that she is on my side, but is this a clear indication of her having romantic interest in me? That was my initial thought, but I don't want to just jump to conclusions. What do you all think?

Clear indication of romantic interest
Probably indication of romantic interest
50-50 indication of romantic interest
I have no idea
