May want to check them out. Do they deliver? Is that your niche?

How much money do you have? Make a list. You need freezers, friges deep fryers. Write a list.

It would be helpful is you give us a little more information. What do you know about pizza? Are you delivering because no others does? What about cheese steaks? hoagies/subs. Are you going after American or other tourist?
