Try mouseplanet web site.. old reviews of all the restaurants w prices but has not been updated for awhile so costs items may be different now... http://www.mouseplanet.com/drr/
Your right! MousePlanet does have a great section that describes each eatery in rather good detail. And just as important to me, is the explaination on how (and IF) the different restaurants take reservations. I think I am spoiled by the priority seating method of WDW!!! I am someone who totally maps out my WDW vacation and makes PS's as soon as allowable....the DL process is so different!
