I went for the hype. Honestly, I think you'll get a lot of 5 star reviews because Swenson's has a cult following, but from an objective standpoint, it's just an above-average burger joint. The drive-in concept is gimmicky to me, and frankly, doesn't always make sense in Cleveland. Do I really want to keep my windows down so you can stick a tray on my car while it's snowing?? Pass.
I had a burger with onion rings and a shake. The burger had that nice soft bun so you can really compress your burger together - I liked that. The onion rings were just onion rings in my opinion. The shake was good, but I can get the same for much cheaper at Steak-n-Shake.
Final verdict: This is the NE Ohio version of In-N-Out Burger, but it's a drive through.
