Ask her to a movie just the both of you no others and see how she reacts and if she accepts, because that would clearly be a date if only you both were to go, unless you want to make it more casual and claim it isn't a date? But if she says yes then good guess she is into you, I wouldn't accept if I didn't like the guy a certain way. Lots of good movies out, then can grab some food after and chat more.
