Hope it's okay if I post the following web site. If not, please remove thread.
Came across a site that had a lot of helpful information, especially for restaurant locations.
www.inyourpocket.com
Home page doesn't look like much, but from there goto City InYourPocket on lower right of screen, and from there, click on city of your choice, then at the top of the next page, click on Restaurants then at next page click on left bar to access the particular type of cuisine. For Prague, they have, for example, a number of Czech-cuisine restaurants listed in about four Prague areas, plus Slovakian cuisine, sandwiches, and on and on.
Other info too, like a few hotels and tourist info, but the restaurant portion seemed the most extensive.
