Several national restaurant chains were shuttered on Tuesday, possibly offering an early taste of what’s in store this year for businesses that depend on free-spending consumers whose budgets are now being squeezed.

The parent company of Bennigan’s, an Irish-themed bar and grill with about 200 sites across the country, filed for bankruptcy, a move that will put hundreds of employees out of work and leave many landlords with empty retail space during a painful time in the real estate market.

A sister brand, Steak & Ale, will also close. Franchise units of Bennigan’s will remain open for now, a spokeswoman, Leah Templeton, wrote in an e-mail message.

The restaurants are the latest casualties in the so-called casual dining sector, considered a cut above fast food. Soaring food costs and a surfeit of locations have hurt the companies’ bottom lines just as Americans are choosing to take more meals at home.
