Hello there.
I'll share my own approach with you, do with it as you wish.
I like to set things up a bit first. A simple conversation where I enthusiastically talk about one of my favourite places which happens to be a local drinking establishment. As it is legitimately one of my favourite places to be the conversation comes across very natural... because it is natural. Then I suggest venturing there with me sometime (no specific date yet), as a rule they smile and say they'd like to. Then we get on to the logistics and make a plan, or I leave it a day or so, it depends on how you feel really.
This approach has been very successfull for me. Generally we venture there, have a wonderful time and somehow seem to end up at my house.
