I need some advice from the internet;

I haven’t been dating for quite a few years now, but I’m finally in a position where I can think about this kind of stuff. I’m a chef that regularly visits my local dispensery after work. Partly because of the cute girl working there with whom I’ve been chatting quite a bit recently. Last week we stood there chatting for over 10 minutes while she left her colleague to help the other customers there. She says her and a friend are coming over to lunch at the place I work at next week. It’s not like she’s been giving me super obvious signs (or I’m just oblivious to them, which I’m not ruling out), but again, she’s super cute.

Is it appropriate for me to ask her out for a drink? I honestly don’t know if I should or not. It does feel kinda weird asking someone out at their place of work and I don’t want to put her in an awkward situation.
