I went by myself to Chuck E. Cheese place on Sheppard and Victoira Park and they won't allow me to come in. How come?

Maybe the restrunt was full.

Many family restaurants have a no single adult policy due to safety concerns.

And all private venues, including shops and restaurants, are allowed to refuse service for any reason  they like.

I guess I have to reserve and get children to go with me if I go to chuck n cheese, huh
