Several I didn't like.
1a the part that means "grandly dines" has exactly the opposite meaning round these parts.
21a isn't a "pescatarian" a fish-eater? The main ingredient of the answer simply isn't a fish!
24a is an indirect anagram (admittedly a pretty obvious one)
27a I had an equally valid second word until it didn't work with the crossers
8d the homophone isn't a fat - fats are solid at room temperature
