Hi Chunke,

Just a quick comment on your question...

Here is a link to a website where you can search for all restaurants
by Metro area

http://www.restaurant.com

Go to the bottom of the page to use this search facility and not the
one at the top of the page which searches for gift certificates in
particular areas (although you may find a bargain or two there!)

Unfortunately it doesn't seem to cover Kansa, Milwaukee, Memphis,
Jacksonville or Indianapolis, but this should get you started!

Happy Counting!

Also 

http://www.restaurants.com/US/USA.asp#Metro

covers Kansas, Milwaukee and Indianapolis...

These sites claim to list all restaurants in Memphis:

http://www.digitalcity.com/memphis/localexperts/category.adp?category=2102G5802&&skip=10

http://memphis.citysearch.com/search?type=grid&flavor_id=2&histoindex_left=neighborhoods&start=1&sort=neighborhood_list&cslink=cs_restaurants_bars_1_0

And these sites cover Jacksonville:

http://jacksonville.citysearch.com/search?type=grid&flavor_id=2&histoindex_left=neighborhoods&start=1&sort=neighborhood_list&cslink=cs_restaurants_bars_1_0

http://www.digitalcity.com/jacksonville/dining/search.adp?type=venue&st=qf&vtid=1&stid=*&tid=*&search=

This was also a good link to a starting point for any other areas you
may need to look up:

http://www.citysearch.com/

Hope that this is the sort of information you were after!

Good luck if you're going to attempt to visit them all!!

Hello,

Why don't you go to http://www.superpages.com and search on your
city/state combinations in the category "restaurant"? Doing that, I
located 3921 restaurants in Miami, 2513 in Atlanta, and 1469 in Boston
(my neck of the woods). Superpages.com is essentially the Yellow
Pages, so I don't think you are going to find better results anywhere
else. Hope this was helpful...:)

look alright.
Just let me know.
