How do you research on the food/cafes to the place you will visit?

I was just wondering there are so many platforms , I usually go through like Yt videos, instagram food bloggers, google search and reviews, random blogs to find the best and famous places of any new city I visit. What if there was a platform which does all of this research for us and provide us with the list of places and their famous delicacies? Is there any app which does that? I have tried chatgpt but not quite satisfied with it.
