Finally getting around to posting these pics - went to the Ramen Show 2009 - won't be going back. Basically just a big field with small ramen shops and long lines. One line for tickets, another line for each shop.
This coming weekend the Tokyo Ramen Show 2009 will be held at the Chuo Hiroba in Komazawa Koen in Setagaya-ku. It will be held from 10 AM to 8 PM on Friday the 29th and Saturday the 30th, and until 5 PM on Sunday the 31st. There is no entrance fee, but there will be fees if you want to sample the ramen. I do plan to go so I will post some info afterwards.
The following link (Japanese only) has the map and more information:
This link has the list of shops that will attend, including Keisuke, Taishoken, Rokurinsha, and others, both alone and in "collaborations".
