Wow! That's a hard choice!!
Our family starts our trip w/ dinner at LTT and ends our trip w/ breakfast at Chef Mickey's.
I guess, though, if I could only choose one, I'd choose Chef Mickey's for 2 reasons:
1.
Mickey Mouse is there!! Along w/ Minnie, Goofy, Pluto, Chip, & Dale normally, & I think Donald is there for dinner. At LTT, Mickey's not usually there - it's only Minnie, Goofy, Pluto, Chip, & Dale
2.
The fun atmosphere at Chef Mickey's - napkin twirling, cheerful music, the monorail running through... it feels very "Disney".
W/ that said, however, I will tell you that, last year, our family had much better character interaction at LTT than we did at CM's. At CM's, the characters (especially Mickey) rushed by all the tables, barely staying long enough at any table for even pics - much less any "interaction". At LTT, we had much better experiences w/ the characters - Pluto played around w/ our DS, Minnie was perfectly darling...
My DH also preferred the food at LTT (served family-style) than the food at CM's (buffet).
However, I think both of those things (character experiences and food quality) are "hit & misses" - sometimes, you go to the restaurant on a good day, and, sometimes, you're there on a not-so-good day.
So I'd still choose Chef Mickey's!
