Oh! You said "go-to" lmao, see how tired I am. This is what hrs upon hrs of school work does to me🤣. Anyways, I actually didn't realize this either until today. But at the end of the day when your taken home.
In Ban's room, in the bottom left hand corner where the map screen is. Click on that and it actually takes you to the night life aspect of Banana Ranch. The only places you can visit at night tho, is the bar, the forest, the ranch, and the love hotel I believe. If you still can't figure it out, then feel free to send me another reply and I'll screen shot where it is in-game tomorrow after my classes let out🙌
