DH and I used the silver plan in December for 14 nights. Here is where we ate using points. For restaurants that serve more than just dinner, I'll note which meal we ate there.
Rainforest Cafe (AK) - L
Brown Derby - L
Hollywood & Vine - B (no longer offered)
Sci-Fi Dine-In - L
Chefs de France - D
Le Cellier - L
Nine Dragons - D
San Angel Inn - L
Teppanyaki - L
Jiko
Spoodles - B and D
Hoop Dee Doo
Citricos
Kona - D
'Ohana - D
Artist Point
Fulton's Crab House - D
House of Blues - L
Portobello Yacht Club - D
Wolfgang Puck Cafe - D
While we didn't have any bad experiences, some places were a better use of wishes than others. Back then, Artist Point and Jiko were one wish restaurants, so we really got our money's worth there. We got the best value at Portobello Yacht Club where our server insisted on adding a lobster tail to our meals. We had a harder time breaking even with the two wish restaurants (Citricos and Fulton's), but we still managed.
We also used wishes for Cirque du Soleil, Keys to the Kingdom tour, Hidden Treasures of the World Showcase tour, Undiscovered Future World tour, and a few souveniers when we had two wishes left on our last day. We loved the silver plan and had a great experience! If you have any questions about the plan or how we used it, just let me know.
