I had the chance to visit Atlantis Pavilions on my trip to Toronto for a cousin's wedding. The views of the city are awesome, and agreed - best from the rooftop deck. The reception was great - the room was beautifully decorated. The clear windows out of the side of the ballroom gave us a breath taking view of Toronto by night!
We had a great set of bar tenders who were friendly and kept the party going....!! We also had some great steak and chicken.
Had a nice time, good food and people which helped make the wedding even better!
