I mean, is it? You swap burgers, pizza, and chicken sandwiches for... burgers, pizza, and chicken sandwiches. Sure, the finishings/plating will change, and you swap out uniforms, but otherwise, it's just a restaurant retheme.
The toughest part of the project will likely be crowd flow, since you'll need walls to go up and restrict that already congested artery to redo the facades. I expect they'll do one side at a time to compensate.
