'Mike and Mary's Pizza' is most likely a place, and a noun is a person, place, or thing. If it is a person's name, a place (such as a street name, name of a place, a city, a country, a town..) it must be capitalized. Just regular English rules.
Now, if the Mike and Mary HAD a pizza, you would not need to capitalize pizza considering it is the object.
