The reason we are asking for the top 6 is because we will have 6 table service meals during our stay. We have already booked Ohana and Teppan Edo. Also, we were hoping to eat at different restaurants than where we've eaten in the past. Those restaurants include: Shutters, Coral Reef, Sci-Fi Drive in, Akershus, Garden Grill, Cinderella's Castle, The Crystal Palace, 50's Prime Time Cafe, Rain Forest Cafe, and Liberty Tree Tavern.
6 in no particular order:
Marrakesh - great food, but losing its sleeper status
Yak & Yeti - another sleeper and great place for TS @ AK
Les Chefs de France
T-Rex
Ohana
Tutto Italia - T/S psycho-max credit value here
From your list of candidates:
Coral Reef - we had great experiences here... told manager we were willing to wait longer for a table "at the tank", manager obliged and we had a great experience...if you are willing to wait, tank seating is possible
Cindy's Castle - 2 TS credits here...we still hit it every trip for character breakfast
Rain Forest - Opt for T-Rex instead; same parent company and better food
Sci-Fi - Atmosphere, atmosphere, atmosphere!! Food is at best decent, but atmosphere makes up the difference...get the Angus burger!!
Askerhaus - Breakfast only...great choice for breakfast
Liberty Tree - decent food...been there several times and will go back, after hitting other joints we have yet to try.......
Honorable Mention
Tusker House (Donald's Safari)
San Angel - See Sci-Fi comments...same apply
Must Mention
BoG - You have to try it!!! We had a great experience, but food was so-so.....won't go back until it becomes easier to grab a ressie. Glad we were able to experience the grand joint, but CAN wait to go back....sorry to mention a place that is tough to secure a ressie...
