I have an outdoor laundromat cafe and I think there's still a place for it on my island. My villagers need something to do while they wait for their laundry to finish haha, plus the more cafes the better imo.
My café is more of a Middle Eastern themed eatery (despite the lack of good Middle Eastern food furniture items), so I don't think that it is necessary to tear it down.
I hope that the cooking update adds cuisine from around the world, because the current lineup is a bit lacking.
