Do I have a real chance at this job?

Two weeks ago I applied to a fast food restaurant (krystals) I kept calling asking if they'd had a chance to look at my application, They had me come in for an interview yesterday, I think it went well because I had worked for the company before in the past and I had a good reference (they also made me tak one of those surveys along with interviewing me, they said for me to call em tomorrow (which is today) they were busy and said they'd start calling all the people they'd interviewed in about two hours (there were two other people there having interviews yesterday as well both male) (not that that makes a difference) two hours have ped and no call, should I call em back and ask bluntly if I got the job? I'm thinking about going there tomorrow to see about it instead.
