A&W is a piece of history. I remember the car service with real glass mugs of root beer and having a Mama Burger. At that time I couldn't eat a full Papa Burger. Fast forward 50 years and I still like A&W. There's something satisfying about it. You go in, the music's on "malt shop" and it's a grand thing.
There are days when I'll go in just for a root beer float, listen to the music and remember my childhood. It's as simple as that - a drink, music and instant nostalgia.
The food's good too. I happen to like their burgers, but I've mentioned before I really DO like burgers. If you want a quick trip down Memory Lane or perhaps you're too young to even know what a malt shop was, A&W's going to give you the next best thing.
