Firstly you need to pick your location. Personally I like to give her options as to what exactly to expect. "Do you drink?" followed up by "Drinks? Food? Or drinks and food?". This is to determine if she drinks or not, and whether to pick a place that specializes in drinks, or just food, or a good combination of both. Pick your location carefully, pick something too fancy and its a lot of pressure on YOU and her, so dont do that. If you only heard of the place definately go in before hand without her. You need to scout out if its a talkable environment, and casual enough. I like to pick hidden gems that are sort of dink. Most of the time and hopefully they have never been before.
Listen listen listen. If you cant hear anything interesting force her to expand a topic, be interested in something. Everyone loves talking about themselves!
Ask her why's shes working there, ask her what her plans for the future are. What does she do for fun? If its something that sparks your interest and is possible be spontaneous! "Hey that sounds super cool, lets ditch this joint and go do that thing".
Learn to create topics from nearly nothing. One time I met this chick on a bus and we talked about her parents nursery for like 45 minutes. Yeap and i was dumb and thought a nursery was some baby care facility, but it was actually a tree growing place LOL so I got some brownie points there

. Date is most likely not going to be about you, its mostly discovering her.
Try to break the touch barrier, simple things like touching her back to lead her through a door you opened for her is great. You need to establish that simple touch like that is casual for you, makes it way easier down the line when you are considering maybe a first kiss

Be yourself, a lot of guys make that mistake after reading watching so many pick up artist things they forget about themselves and end up being a template for a good date. As others said, you HAVE to get rid of that idea that you are a boring person.
If it ends up being boring as hell, maybe just keep it at that. A date between two work friends, and will continue being friends. Dont be so nervous, most girls especially if they have looks have been on WAY worse dates. You already making a conscious effort to make it a good date is a +1 already, guarantees you wont be the worse date of their life.
