tidy up

【原文】
McDonald's, which has more than 14,000 U.S. restaurants, performed well throughout most of the economic downturn by sticking to its strategy of remodeling and tidying up restaurants and rolling out a steady stream of new menu items at a range of prices—from inexpensive snack wraps to more costly fruit smoothies—intended to appeal to more consumers.
