Time Out says
One of the city's top attractions is the aquarium that's packed with interesting sea creatures. But the best show of all is the sea lion who swims above your head in his glass, doughnut-shaped pool. Looking up at him with the city sky in the background makes us want to nickname him Super-Sea Lion. Don't miss the recently re-opened observatory Sky Circus on the top of the Sunshine 60 building.
