GEB is a great book, and I've probably read it at least 3.33333333... times over the years. As a late teen it blew my mind. But I'm not sure I'd recommend it as a route into Gödel's proofs [1]. The book covers a lot of other ground too, and is notoriously digressive and quirky (looking at you, dialogues).
Instead I'd recommend Gödel's Proof by Nagel and Newman for a conceptual intro.
[1] I'm not a mathematician, so my understanding is necessarily informal.
I really like GEB.
Most proof of the Gödel theorem use the primes encoding that is makes all the operations very unintuitive. But GEB uses just ascii and a lot of the side task get obvious. (It uses base 20 instead of 256, but it's the same idea.)

It is super mega ultra notoriously digressive and quirky.
I can second this as a wonderful introduction to the proofs. This is the book that got me into logic and formal methods.
I’ll never understand how GEB was using math, art, and music to explain consciousness (and Hofstadter himself still thinks no one understood it), but Nagel and Newman did a great job explaining why logic as a mechanical thing has only a tenuous relationship to concepts we understand, and that helped me crack at least a little bit of the mystery I was after when giving up on GEB.
I have not read GEB but I thought his second book, I am a Strange Loop, did a pretty good job of connecting the idea of self referential loops (like in godels proof) to consciousness and art and such.
I am a Strange Loop is basically GEB but written properly instead of being a random collation of ideas.
Unrusprisingly, since many years went by. But I still love the quirkiness of GEB
(Also, he has other books between the two, I deeply enjoyed Le Ton Beau de Marot, about translations)
Thanks for the suggestions. Just checked out some of Le Ton Beau de Marot, will most likely read the rest.
Actually, I was recently wondering whether poems can be interpreted as "efficient" computer programs. Words in a sentence/essay just connect different objects in space and time (syntactically and semantically) to form some concept, kind of like a program. A poem just uses higher order abstractions (imagery) to express the same concepts in fewer words.
So this book should be great!

As Flannery O'Connor wrote, "The result of the proper study of a novel should be contemplation of the mystery embodied in it, but this is a contemplation of the mystery in the whole work and not or some proposition or paraphrase. It is not the tracking down of an expressible moral or a statement about life." We don't read literature with the hopes of a book laying out a precise thesis and incontrovertibly demonstrating it.
If you come into GEB expecting a scientific explanation of consciousness (like I did, when I first read it) you walk away confused and maybe disappointed. Hofstadter observed something transcendentally beautiful about self-reference and had a spiritual or religious revelation that, for him, related it to consciousness, and he attempted to convey that beauty and spiritual revelation in - appropriately self-referentially - a book that embodied it. You're meant to appreciate it in your heart and soul, not (just) in your mind. It's literature, not science.
Thanks, that's a fantastic quote that gets at the heart of how to appreciate GEB.
