My lover feel like we should get out and he would like to explore various fantasies,. I can not imagine to join his other than to support him, is the a place where we can be private alone or do we have to take part in the activities. Can we have lunch and a drink and leave?

I don't understand, is your lover's fantasy to have sex outside of your normal bedroom/house? Or do you want to introduce new people to your sexcapade?
Where does lunch and a drink fit in? Why leave after lunch and a drink?

#confused

I think she is saying she is supporting him but wont join in the activities? And wants to meet the girl beforehand? And if they dont want to go through with it they wont have to? Sure have drinks and a dinner but be sure to pay the lady dining with you too

The person might be referring to a swingers / gentlemens club?

@Kitty: Thanks for the translation! That makes sense.

That makes sense too

If I may, she does not want to join her partner and the girl, but she wants to meet the girl first and seems like if she approve of the girl she will leave and let het partner and the girl have some fun.

I'd suggest contacting Heaven on Earth.

However, I'd also caution about this, from what I've inferred it's your lover who wants some variety and not you. You just want to do a vetting on the person he chooses.
Ask yourself if this works both ways, can you also have some variety without your lover getting jealous? If you are just doing this to keep your lover happy and have not bought into the idea of sharing then you are opening yourself up to a whole lot of emotions and heartache.
Make sure you enter into this arrangement with your eyes wide open.

I have met many female partners who were not into the whole thing but did it for their men. In some cases the experience went off fantastically and others not. In a work situation I am always uncomfortable when the lady is not 100% into it. But my experience with couples is limited. But, I always say you have to try it. at least once.
