Coffee and baked goods have always gone together, like rock 'n' roll, yin and yang, and bald-eagle hatchlings and William Howard Taft's toupee. Introduce your mouth to a dazzling duet with today's Groupon: for $10, you get $20 worth of café fare at Retro Shot Espresso.

Retro Shot Espresso stocks its caffeine-filling station with creative coffee and drinks served amid 1950s-themed décor. A salty-caramel macchiato ($3 for 16 oz.) can perk up groggy office workers when sipped or splashed into hair, whereas a double buttercup ups the espresso ante by fusing white mocha and peanut butter ($3.25 for 16 oz.). Signature coffee drinks with nostalgia-evoking names include Americano Graffiti and Jitterbug and are made exclusively with organic and fair-trade Avion coffees. Customers nosh on croissant breakfast sandwiches ($2), bagels with cream cheese, and muffins ($1.50) amid the cozy coffee stand setting and vintage wall hangings, depicting a pouty Marilyn Monroe and a triumphant President Eisenhower posing with his beloved whoopee cushion. Each month, the staff holds a nonprofit Sunday to support a different charitable cause.

Retro Shot Espresso has moved locations and is temporarily closed. They will reopen on April 15.
