Takeout Recommendation Dataset (TRD) from Meituan Takeout app

This is a takeout recommendation dataset (TRD) which contains a vast amount of meta information from Meituan Takeout app. We collect orders from 11 commercial districts in Beijing between March 1st and March 28th, 2021. The first three weeks of orders are as training, while the last week is used for testing to avoid data leakage.
