Gurugram-based restaurant aggregator Zomato has asked its partner restaurants under its 'Gold' program to serve the 45-day notice. This comes after about 300 restaurants under the National Restaurant Association of India (NRAI) on Thursday decided to delist from several reservation and food platforms over deep discounts. These included Zomato, EazyDiner, Nearbuy, MagicPin and Gourmet Passport.
