Whether you are a comic book collector, or a casual comic book reader, you will find a visit to Isotope worth your while. Anyone living in Hayes Valley who likes comics and graphic fiction, knows this place, and that is not just for its impressive collection of books, though it is very commendable. This lounge-cum-comic-book-store brings the best of both together to create a unique gallery-cum-reading-room kind of place, where customers can lounge around on the leather sofas while reading a book or two, or attend a live event featuring known names in the comic books business. What's more, you can tag along your furry four-legged friend to partake in this experience, since Isotope welcomes dogs.
