We booked Radisson Blue in Paschim Vihar for our wedding and it was a real grandeur venue.The ambience was amazing and the staff was well trained in dealing with people.They have their own catering and decoration so if you want to get someone from outside to make it a little heaper you cant. They strictly prohibit the enntrance of any of the outside vendors and their services are very costly. The decoration was very expensive. But overall it was a real nice experience with them.
