Well,
Mike G, never having bought an octopus, I can't speak to that. But squid are packed
au naturel, full of goopy guts, with quill, beak, and beady little eyes attached. It's quite an experience to gut a kilo of thawed squid, let me tell you...
Lizamann, the Asian stores on Argyle/Broadway would be a pretty safe bet for finding frozen squid, goopy guts intact, very close to Lakeview. Start there...good luck, and have fun!
