Do any substantial USA cities NOT use a gridded street pattern?

Question

On a recent trip to the USA, a friend of mine said she was struck by how all American cities and most towns that she saw were built around a gridded square, with few curves in the road. I understand why this is, but I am curious.

Are there any sizeable towns or cities (that a foreigner might have heard of, preferably!) that exhibit a more 'organic' growth pattern, as per a western European city?

Thanks!

Answer 1

Houston Texas or Denver Colorado is awful no grid whats so ever! You take a wrong turn and you are in a diffrent city!! Even when I lived there I still got lost all the time.

Answer 2
