Sorry, might be being silly but I can't work out how to set up a Dizzy's in a new town?
Once you unlock Dizzy's, you will have a new tab on your home screen that lets you manage it. You need awareness for people to come in, which you can and should raise before anything else. Afterwards you can hire people either through a hiring ad or with this recent update, through your contacts. I would suggest spending at least 10K or more on the highest level of advertisement before you hire people to turn a profit.
