The latest list of permanent restaurant closures include a top fine-dining bistro in downtown Santa Ana, a diner in Old Towne Orange and another loss for Pinkberry.

Take a look:

• Old Towne Eatery, which opened in August 2014, will be closed as of Monday. In an Instagram announcement, owner Ralph Sandoval said Sunday would be the restaurant’s last day. “My partners and I have decided to sell,” he said. “It was not an easy decision but ultimately it was in all of our best interest.” Sandoval, who previously owned Los Cabos Mexican restaurant in Orange, said a Thai eatery is taking over the space. The restaurant space is tucked in the alley of The Clark Building in downtown Orange, next to Jalapenos and Zito’s Pizza.

• Finbar’s Italian Kitchen, which used to operate a handful of restaurants in Orange County, closed its Costa Mesa location in late March. The old-school Italian restaurant previously operated in Seal Beach and Rancho Santa Margarita. Those locations have since closed. The Metro Pointe eatery closed because the landlord did not renew its lease, Finbar’s said on its Facebook page. The restaurant plans to make a Seal Beach comeback by reopening in April at 1041 Pacific Coast Highway, the company said. The owner of Pizza Press, a build-your-own pizza and craft beer chain, confirmed he would be moving into Finbar’s space in Costa Mesa.

• TGI Friday’s in Laguna Niguel is closing in late April. A manager answering the phone said the last day of operation would be Monday. She cited a lease issue for the closure and referred questions to the franchisee’s parent company The Briard Group. The company operates several Friday’s restaurants in Southern California. According to state employment records, the closure impacts 51 employees.

• Pinkberry at The Tustin District has closed. This is third Pinkberry to shutter in recent months. In November and December, two Pinkberry shops closed in Brea and Santa Ana. In mid-December, the froyo brand, founded in Los Angeles in 2005, was purchased by Arizona-based owner Kahala Brands.

• Jamba Juice at the Market Place in Tustin closed March 1. It will be replaced by Nektar Juice Bar this summer, Irvine Co. officials told the Register.

• The owners of Little Sparrow, a highly praised downtown Santa Ana bistro when it opened in 2013, closed the restaurant over the weekend. Its last day of service was April 17. The owners said it would reopen the restaurant as BlackBox. It “will retain Little Sparrow’s award-winning craft cocktail program,” the owners said in an announcement Friday. They said more details would be revealed later this week, according to the BlackBox website. The link indicates the new restaurant will focus on burgers and beer.

• Smashburger in Irvine on Alton closed this week, according to an employee answering the phone at the Aliso Viejo restaurant. The location also has been removed from the chain’s website. The Denver-based better burger chain opened its first two O.C. restaurants four years ago in Aliso Viejo and Mission Viejo. Since then, the company has been slow to add new locations as other invaders — Habit Burger Grill, Five Guys — have stepped up their presence in Orange County.
