Chen opened her first restaurant,
Joyce Chen Restaurant, at 617 Concord Avenue in Cambridge in 1958. She promoted healthy Chinese cooking and refused to use
Red Dye No. 2 and other food coloring at her restaurants. For Chinese-speaking and English-speaking staff and customers to communicate more easily, Chen introduced the practice of numbering menu items. The first restaurant operated for thirteen years, closing in 1971. In 1969, members of
Bolt, Beranek and Newman's IMP team ate at Chen's restaurant, which was located next door to BBN, when they were working on the first IMPs to create the
ARPANET. After her divorce in 1966, Chen sold the original restaurant to her ex-husband, who converted it in 1972 to a Japanese eatery called Osaka. It operated for 21 years and closed in 1988. In 1969, Chen opened her third restaurant, a much larger space seating 500 people, in an existing building located at 500 Memorial Drive in Cambridge. This restaurant, also called
Joyce Chen Restaurant, benefited from its proximity to MIT and Harvard. However, the restaurant closed in 1974 when the building was demolished so that the MIT dorms
New House, and later,
Next House, could be built on the site. New House was jokingly known by MIT students as the "Joyce Chen Small Living Place" for a time. In 1973, Chen opened her fourth restaurant in an elegant
Modernist custom-designed building at 390 Rindge Avenue, near
Fresh Pond. The building, designed by Alan Ahakian, was described as "marvelously secluded behind a baffled garden wall that focuses around a single tree". The restaurant, also called
Joyce Chen Restaurant, seated 263. It operated for 25 years and closed in 1998. In 1975, Chen's eldest son, Henry, opened a fifth
Joyce Chen Restaurant on
Cape Cod, but it closed after a year and a half. Her other son, Stephen, managed a downtown branch of
Joyce Chen Restaurant, which operated from 1988 until 1994. Chen was a warm hostess who formed relationships with many guests, including
John Kenneth Galbraith,
James Beard,
Julia Child,
Henry Kissinger,
Beverly Sills, and
Danny Kaye.
Nathan Pusey, a former Harvard president, called her eating establishment "not merely a restaurant, but a cultural exchange center". She would often mingle with guests, including those with no celebrity. ==Career highlights==
