best mobile app idea

this is a mobile app idea that I would use every time I eat out. So it's a location based restaurant discovery app. So the main homeview would just be a map of where you are and it'll show all of the open restaurants that is around you and you'll easily be able to see the type of food they have, price range, reviews from Yelp, Google reviews, and other apps, and the estimate wait time. The reason why I think this is better than just like looking it up on Google because a lot of the times I just wanna go somewhere close but weigh all of the possible options without having to kinda predetermine what kind of food I want, look up that food and just hope that it's nearby somewhere. Especially when I'm travelling, I'm looking to eat somewhere where I don't have to Uber and I'll just be able to look at the map and pick like a good restaurant with the food I want at the right price point and short wait times. If I were to look that up on Google, it would not give me great results and honestly I have a really hard time deciding and I like read through the reviews and it's not that helpful. It just recommend so many restaurants that are like too far away or is that an inconvenient location or something. So I'll use this location based restaurant discovery app. Honestly I don't know how many other people want this like I do. I just be really niche problem for myself. Let me know if you'd build it and follow me for more startup ideas.
