Is the Chinese food in Incheon's Chinatown different?

‌I really love Chinese food
(Jajangmyeon, Jjamppong, Tangsuyuk, etc.)
I'm planning to visit Wolmi Island in Incheon around next week,
and after that, I'm thinking of heading to Chinatown to eat Chinese food.
Is the taste usually different from your typical Chinese restaurant?
My original plan was to just watch the girls on the Disco Pang Pang at Wolmi Island,
then go to a raw fish restaurant with an ocean view for a plate of sashimi,
and then eat at a Chinese restaurant nearby (I know a place in the Wolmi area).
However, I've heard that the Chinese food in Chinatown is different,
so is it worth making the extra trip to Chinatown?
