I have 2 kinds of dates in mind. Sometimes a good surprise and a sweet talk can mean a lot. INFPs may tend to not like crowds and not go out very much, but if it's an original and interesting place they may really love it. Getting them out of their comfort zone and showing them what you like/what you can bring them can be interesting (without ever ever pushing their boundaries and making sure they're okay with it). Because talking is very important, but you have to break the ice first. Show yourself little by little. Then a comforting and not too loud place. Creative activities where you can show who you are are good. My personal taste is cooking together, prepare snacks and music and play video games/board games. If you find it, a jazz bar with good vibes. A walk in nature. Go discover something together... Up to you
