From the outside you can’t tell, but once you walk inside the Hyatt you are dazzled with a futuristic sci-fi structure. The atrium of the hotel even holds the Guinness world record for the largest hotel lobby. At the top of the building there is a revolving restaurant called the Regency Club Lounge where guests can overlook the bay and the city as it rotates 360 degrees. Unfortunately it’s not open to the public and you can only dine inside if you’re an elite tier guest or book a room with access to it.
