Every Thursday evening, the Academy of Sciences ditches its scholastic daytime act and transforms itself into a real-life night at the museum. Snag a seasonal cocktail, and soak in what is perhaps the most awesomely bizarre bar in the city.

For a mere $12, NightLife visitors gain access to the oldest scientific institution in the West, but this time with a bar and a band. Whether it’s the albino alligator next to the dance floor (separated by some very thick glass), or the sharks on the prowl overhead (also separated by some very thick glass), each exhibit offers an up close and personal glimpse at the natural world. And cocktail in tow, museum-goers can meander through the dim aquarium dungeons– complete with water snakes, glow in the dark jelly fish, and a fleet of piranhas.

Or, if rubbing elbows with amphibians and bad dance partners gets to be too much, make sure to step outside to the Observation Deck on the top floor. This “Living Roof” presents a view of the city amidst its millions of native plants and seven rooftop hills. Afterward, the hungrier folk find their way to the museum cafeteria – for only $3, the chicken and pork buns are a delectable treat after an evening of drinking, dancing, and hanging out with octopi.
