An owl popup bar is coming to London, but only for a short time, and nearly 50,000 people are scrambling to get in.

Yes, that's a pub with actual owls.

Locappy, an app startup, and an English conservation group called The Barn Owl Centre say the event is called Annie the Owl, because it will feature an owl named Annie, and some other owls, too, who will make a one-week appearance hanging around a bar in the Soho neighborhood of London.

The event will run every day during the week of March 19 to 25, during the owl-friendly nocturnal hours of 8:30 p.m. to 2 a.m.

A £20 ticket per person will buy two hours of "unique owl indulgence" and two cocktails at the pub, which hasn't been identified yet.

The cocktail menu includes a vodka and gin drink called The Hoot and the Owl-Presso Martini, a Kahlua and espresso twist on the vodka drink.

Because of demand to get in, organizers say they're conducting a ticket lottery. At last count, more than 45,000 bidders had filled out the online ballot.

And to ease any safety concerns, they say "all owls are trained to be around the public and will be accompanied by professional falconers."

Annie the Owl isn't the first animal themed pop-up. Last year, for example, Purina temporarily opened a cat cafe.
