Answer:
The predicate nominative in the sentence provided is: My favorite place or favorite place
Explanation:
Predicate nominatives renames the subject, much like how in the sentence you are renaming your 'local video store' as your 'favorite place'
"The local video store is my favorite place"
The local video store = my favorite place
Another example would be:
"She was a monster"
By renaming 'she" as a 'monster'
She = Monster
