I liked the location-based searches that the app offered, so I downloaded it to help me find restaurants whenever I was in a neighborhood and without a specific place in mind. I used it twice. The first time, the restaurant I decided to visit was no longer in business. The second time, the address and map location were incorrect.
Not only does the information need updating, it needs enhancing -- there are no hours listed for the restaurants (no even "lunch only" or the like) and there needs to be more details (e.g., 2nd floor of Hanhwa Building).
