After 37 years of business, Armand’s Pizza in Tenleytown will serve its last pie on June 30.

“Our rent is very expensive—$12,000 a month,” says owner Ron Newmyer, son of the restaurant’s founder. “The cost of doing business these days is very, very different than even ten years ago.”

Armand’s Pizza has five additional locations in Virginia and D.C. (plus one in Delaware), which will all remain open (Newmyer’s family operates two; the others are franchised). But Tenleytown was the first.

The closing was first reported by NBC Washington.

Ron’s father Lew Newmyer opened Armand’s in 1975. “It was the first deep dish pizza in Washington, D.C.,” says Ron Newmyer. “It was the first place in D.C. where people took pizza seriously. Before that, pizza was something you got in a bar and ate while getting a pitcher of beer.”

Celebrities took notice.

Amy Carter celebrated her birthday at Armand’s at Tenleytown in 1977. Chelsea Clinton did the same in 1994.

Michelle Obama was at the pizzeria two years ago.

The restaurant will host one last birthday bash on June 10. That’s when founder Lew Newmyer turns 90.

“[It’s] bitter sweet,” says Ron Newmyer. “Happy he’s turning 90, sad that we’ll be down to our last twenty days. Didn’t expect he would live longer than the business.”
