Signature: well only one choice and often considered one of the best sig at wdw is the Brown Durbey
Ts: not sure what best is. Lots of different styled and themed experience.
Qs: backlot express. I like their food, the complimentary soda refill station, the theming is nice, it’s air conditioned (with some outdoor seating too) and there is the Star Wars Jedi academy to provide some entertainment. I think rizzos and abc food is abysmal. The outdoor eating including Rosie’s etc down sunset Blvd is ok on food but there is no air conditioning and you often need to wait in different lines for families with varied tastes. If it’s a nice day it’s alright but my go to is always backlot express.
