Rahaaland:
As a matter of fact, in planning the pizza pilgrimage, I used Google maps to find out what pizza restaurants were in a given city or town. But all I did was go to the maps page for Google, type in "Pizza" and "[city], [state]". That brought me the results I wanted. Then I could go to a regular Google search, type in the actual restaurant name with the city and state names to see a) if they had a personal website, and b) any comments others might have made about a restaurant's pizza. I don't know that you could make it any simpler than that. Btw, sometimes I took certain comments with grains of salt depending on what was being said. And a restaurant not having a website was not a deterrent. Almost none of the pizza places in Dixon, IL had a personal website, except the chains.
