The space travel/internet cafe.
There’s a cafe at street level with comfy sofas and gaming pc’s. An observatory and two giant rockets. You need MOO to place the gate on the fence – they still work though.
And in the basement, there is a bullion store – it’s all swipeable! – an infirmary, though that’s only for show! A space travel portal, dormitory, bathroom, gym and massage facilities.
I’ve also had one of the scientists build and upgrade the rockets so they’re safer for even the most novice space tourist to use.
