Chope App is a restaurant reservation app set up by a friend and ex-Bain colleague of mine. Available on IOS and Android, you can search for restaurant recommendations by location, type of cuisine, price, and many other criteria.
Restaurants offering 1-for-1 or 50% off deals
The app also has a great listing of restaurants that are currently running 1-for-1 or 50% off promotions.
