Adds details in paragraph 6-8

Feb 12 (Reuters) - Restaurant Brands QSR.N QSR.TO reported fourth-quarter comparable sales above estimates on Thursday, helped by resilient traffic at its Burger King and Tim Hortons chains.

Value-focused menus continue to attract budget-conscious diners, as fast‑food chains lean into affordability while pricier rivals struggle.

The company's Burger King chain introduced '2 for $5' and '3 for $7' value meal offers over the last year.

McDonald's MCD.N also topped estimates for its fourth-quarter global comparable sales and profit on Wednesday, helped by meal deals and strong marketing promotions.

Same-store sales at its Burger King outlets in the U.S. rose 2.6% for the quarter, compared with analysts' expectations of a 1.5% rise.

It posted an adjusted profit of 96 cents per share for the quarter, topping estimates of 95 cents per share, according to data compiled by LSEG.

The company reported quarterly same-store sales growth of 3.1%, compared with estimates of a 2.8% rise.
