We've done both breakfast and dinner here correct me if I'm wrong but characters only at breakfast or dinner not for lunchtime?
Not really much difference between either the characters still will be there we preferred breakfast to dinner, little quieter and not as hectic as dinner. But it's fine for both!
We now have discovered inventions and much prefer this to cafe mickey to meet the characters. But it is dearer than cafe mickey so it all depends on budget tbh and wha you want to spend. The setting is a lot calmer and the food although buffet is plentiful and yummy.
Have a wonderful trip!
