Ranked in these QuestionsQuestion Ranking
Pro Clean UI
Zomato has an easily understandable UI.
Con Poor search algorithm
If you search sushi in New York City, the #3 result is Five Napkin Burger, which, while it serves sushi in addition to its famous burgers, is no where close to being the #3 sushi restaurant in NYC.
Con Smaller user base
Serving much the same functionality as Yelp of crowd-sourcing restaurant reviews, the much smaller user base is a serious weakness.
