Is there a chance for more?

I'm in a new city to handle a contract project. The project lead is a gorgeous Brazilian woman that has come to the US site for this company to lead it, so technically she's my onsite manager. We went out to a bar last Saturday night. Good vibes, convos, drinks. When time to leave she insisted we ride Uber share. I told her due to logistics, we should go separately. She then, goes to maps from Uber all for me to show her where I resides. We left separately. She acted differently on Mon until about Weds.. not as bubbly, a little reserved. Recollecting her vibe before and after the outing in hindsight, I assumed she wanted a night cap with the Uber suggestion and she feeling slighted when I said for us to get separate Ubers. So Thurs, she asked me to go to NBA game Friday. I said yes. We went, again good vibes. After the game, I insisted we head to a lounge afterwards for drinks and dancing. She stated she's had a long work week and is tired, and wants to go home. She has yoga Saturday morning. We chatted outside while waiting for Ubers about various things. I did throw one line in telling her how she has modeling qualities... And is very photogenic. She replied that she didn't see it. My Uber came first, I told her bye and she in turn initiated a hug. I told her to be safe and I left. Minutes later she texted me that she was home. I would love a "night cap" with her, don't get me wrong but I'm a little confused on her angle. it's a little tricky to make the manly initial "real" conversation due to the work dynamics. Am I in the friend zone, or do I have a chance for more while I'm here (5 months). If I have a chance, how can I execute to see if there's a "nightcap" opportunity? If it wasn't the fact that we work together I'd already have my answer because I would've really put out there how I feel about the situation.. with clas of course. I never did outings on this level with a colleague before so this is uncharted territory. What are your thoughts?
