Wongnai.com is a Thailand-based restaurant review website and mobile application, much like Yelp in the US. Wongnai (which means ""insider"" in Thai) allows users to search for restaurants by location or category. Users can browse through restaurant information, user reviews, and photos from over 100,000 restaurants in Thailand. Wongnai's location-based application is available on various smartphone platforms such as in iOS, Android, Windows Phone and Blackberry.
