A lot of this feels pretty superficial. I was kind of hoping to see more of an analysis of how Gibson uses foreign words for texture, rather than a simple glossary.
The essay misses one interesting detail: along with the Chatsubo, another restaurant Case visits in the first chapter of Neuromancer is "a teashop called the Jarre de The". Both names mean "pot of tea" -- one in Japanese, the other in French. The juxtaposition is more than coincidence.
