A New York restaurant is celebrating 70 years of business by bringing back pricing from the 1950s. 

Serendipity3 has been a New York City must-go for many since September 1954 — and this year it's celebrating 70 years. 

In honor of that, the restaurant and general store announced that it will offer its popular menu item, the "Frrrozen Hot Chocolate," for just $1 — for one day only on Sept. 18.

Serendipity3 noted that the go-to sweet treat was priced at $1 when the spot opened in the 1950s, so the restaurant wanted to bring the nostalgia back for one day, according to its news release. 

Those looking to grab their $1 frozen hot chocolate can book a reservation at either the Upper East Side or Times Square location, which opened last week, ahead of the day.
