While I love the Anchor, mentioning I was from Hutchinson was more about the little places in South Hutch especially the ladies that provide the delicious mexican food during bingo nights at Our Lady of Guadalupe.
I'm not sure about quality, but SW Kansas definitely has the authenticity. I've never eaten Mexican in KC, so I truly don't have a comparison, but you can't throw a rock without hitting a delicious Mexican restaurant in certain parts of Garden City.
All that aside if you don't try Rusty's Mexican food at least once you are doing yourself a disservice. And if you are in MHK and are looking to eat Mexican then go get super PAKd with your buds. . .it makes sense to eat there then hit the Ville. No one will argue that Lucha is hands above better. . .but it is small and often packed. Fuzzys is alright, but I'm a large proponent for keeping my money local as often as possible.
