The Atomic Bar and Lounge will open Friday at 4 p.m.

Spouses Rachael Roberts and Feizal Valli are opening the mid-century modern, 1960s-themed bar at 2113 1st Ave. N. Both are formerly of the Collins Bar on Second Avenue North.

"It's a one of a kind bar, and it's a very Birmingham experience," Valli said. "It's more about the person that walks in here than it is about us."

The bar will be open from 4 p.m. to midnight on weeknights and from 4 p.m. until 2 a.m. on Friday and Saturday. It'll be closed on Sundays and Mondays.

The bar's signature drink is four variations on the "Sex Panther," a play on the old fashioned, but as Valli describes it, "more aggressive." Included in the cost of the cocktail: a panther temporary tattoo.

Valli and Roberts aim not to take themselves too seriously. Nowhere is that demonstrated better than the costume menu: customers can choose from about a dozen costumes to wear while they're at the bar, ranging from a shark to Princess Leia to a chicken (It's free, but you do have to leave your credit card with the bar while until you return the costume in one piece).
