Must a banquet hall have in-house catering to be successful?

As many of you know, I’m still searching for my career. One thing for sure is I’ve always had my heart set on owning by own business but I didn’t know what. Lately I’ve been very interested in owning a banquet hall that provides receptions and also other special events such as prom, corporate, etc.

I see a lot of places offer catering. I didn’t have my heart set on starting out as a restaurant type place. I know a lot of people sometimes want to bring their own food or own caterer. Is it still profitable if you aren’t a restaurant type banquet? I’d more so plan on developing relationships with restaurant owners and caterers some how.

Maybe in the future once things are up and running I can go towards a restaurant/serving type place. Of course, right now I’m researching as much as I can to see if this is fitting. So basically I’m all talk right now.
