The Walgreen Company agreed to sell 91 Wag's family restaurants to the Marriott Corporation, a move that will enable it to focus on its drugstore chain, which is the largest in the United States. Terms were not disclosed.

Walgreen, which has 1,400 drugstores in 29 states and Puerto Rico, said last month that it wanted to sell the Wag's free-standing restaurants. The units being sold are 24-hour operations in Florida and Illinois and include four units under construction. Walgreen still has another 27 restaurants, a few of which operate in malls and are not 24-hour operations, a spokeswoman said. But she added that Walgreen would eventually be completely out of the food business.
