The 25-year-old Ruby's Diner at the Seal Beach pier closed Sunday.

The restaurant, part of Irvine-based The Ruby Restaurant Group, was unable to come to an agreement with the city during renegotiation of the location’s lease, according to reports.

Ruby’s totals nearly 40 restaurants, with an estimated $40 million in annual revenue. Most of its restaurants are in California, including locations on the Balboa and Huntington Beach piers.
