There is a restaurant with inside and outside seating space facing the seafront and a Garden Lounge Bar with inside and outside space overlooking the water gardens, Town and Italian gardens which adjoin the main High Street and the Sovereign Shopping Centre.  The Winter Gardens had a 10 million pound make-over a few years ago and recently had a 5.5 million make-over which makes this venue a very beautiful place to hold an event such as this.
