Mimi Cheng's wraps up 12 years in the East Village next month

Mimi Cheng's is closing its East Village quick-serve restaurant after 12 years.

Owners and sisters Marian and Hannah Cheng announced that Sept. 11 will be the last day at 179 Second Ave. between 11th and 12th streets, as the lease ends. 

"This 12-year story was built by you, and we're endlessly grateful," they wrote on Instagram. 

The closure doesn't mean the end of Mimi Cheng's. The sisters said they are shifting their focus to growing the company's frozen dumpling business, which is now sold in stores nationwide. 

"The dumplings aren't going anywhere," they wrote. "They're just getting a bigger home." 

The sisters opened the East Village location in July 2014 ... naming the business after their mother, Shirley, whose nickname was Mimi.

Why Mimi Cheng's is temporarily closed

A story we didn't get to mention this past week... Mimi Cheng's is temporarily closed here at 179 Second Ave. between 11th Street and 12th Street.

Door signage for patrons points to a "building issue."

There are more details in an Instagram post, which cites a gas outage in the building ("looking at you, Con Ed 👀").

The Taiwanese dumpling shop operated by sisters Hannah and Marian Cheng opened in July 2014.

Last fall, a frozen variety of the dumplings became available at tri-state Whole Foods.
