I've done that with the gym in DSV, and I like making restaurants out of maxis lots that I tend to use all the time myself so I know they work. I like my version of the Fountanview Penthouse, the Fountanview Diner. There's also the Dead Grass Diner from BB and a diner version of the salty paw cafe or whatever it's called in BB. But I'm note sure if I've uploaded all of them or, if I did, how recent they are :) but there's really lots of people that make awesome repurposed builds. Just search for the original name of the lot and filter by lot type :)
