Why are Sims moving in to my restaurants ?

So I started a new game and placed my restaurants and bowling ally in the same old places in Newcrest . Now I cant use them and Sims keep moving in to them ... HELP !

Probably a stupid question but when you placed the building did you make sure you had set it to lot type restaurant and not residential lot the.
