No mention of backyard burgers? Those are y favorite chain problaby though I haven't had one in over 10 years.
I think In n Out is probably the most overrated fast food chain. Not the worst at all, but low. I haven't had shake shack.
Five guys, the wall is covered in praise from cities around the country, I think it's very overrated too, but more justified than In n Out. It does seem a lot like a homemade burger, and is a satisfying burger, but there's just something missing in the taste - when I eat one, it just seems 'it's ok, and seems decent quality, but not exciting.'
Something keeps me going on rare occassion to In n Out, maybe the combo of freshness and value.
Most independent places' burgers just seem better.
For just one example we have a 'Philippino fusion' type place with an 'Adobe' burger whatever that is that is nice, with a pineapple slice - and you can get truffle oil fries.
