I went in the airport last weekend and got a quarter pounder meal.
However, I go probably 2-3x a month. And almost always get a McDouble and medium fries.
Their prices have gotten higher, but imo the beef has also gotten better.
But if you actually do go semi-often, the deals in their app are surprisingly legit.
I can usually get a McDouble, fries, and drink for under $5.
Edit: the move is free drink with any purchase of medium fries. They have that deal seemingly permanently active in the app. Then a McDouble is like $1.89 or something like that. They are still a damn sight cheaper than Chipotle or any of the fast casual places. However, I miss the old dollar menu the new one kind of sucks.
Edit2: sausage egg mcmuffin with cheese is also a damn near perfect breakfast sandwich.
