LOL, it seems like every time we declare a "must-do" restaurant, Disney jacks up the price, cuts the entertainment, changes the service style, and/or blandifies the menu to remove all the reasons we liked it in the first place.
Two of our favorites that have endured are Yak & Yeti (for lunch on our AK day) and Raglan Road (for our first or last dinner), which have never let us down, and on our EPCOT days, my husband almost always asks to go back to San Angel Inn. We ask for a waterside seat (and explain we're happy to wait as long as it takes), and the beautiful view of the water in the perpetual twilight inside the Mayan Pyramid makes the food almost an afterhought.
