The group bought the building last year and Fitzsimmons Architects is responsible for the high-style design.
Gun is a Japanese pub, with beverages and street food inspired by travel to Japan and other U.S. Cities.
Owners Rachel Cope and Chef Jeff Chanchaleune will offer skewered meats and vegetables cooked over Japanese charcoal and other shareable plates.
In addition to a unique and striking interior, Gun also features a south-facing patio with a steel and fabric awning structure, overlooking the Paseo pocket park.
Gun will join newly-opened Paseo eateries OSO, Scratch, Buttermilk, Red Rooster Holey Rollers and Mayan. Soon to come is Frida and The Daley, which will add to Paseo favorites Picasso Cafe, the Paseo Grill, and Sauced.
