Due to a chain of unforseen events involving a thunderstorm and the consequential stoppage of all outbound trains(!) we ended up at Ichibun again this evening.
 
After stepping inside we were immediately given a dish of おから (okara - fried soy pulp and vegetables) - I wish I'd taken a photo but unfortunately I was so surprised to see it (as I love the stuff) that I wolfed it down before I remembered to take one. After seeing the evening menu we immediately decided to try the モヤシのオイスターソース炒め (bean sprouts and pork fried in oyster sauce) and salami pizza and they were great, particularly the bean sprouts as they were really salty (I love salty).
 
Of course those were just a starter really (erm) so we then went with 生姜焼き (pork in ginger on rice) and their ramen. Finally the restaurant owner brought us out desserts of home-made orange-flavour jelly (again no photo due to wolfing, sorry) which was a great finish.
 
The whole meal cost us 1800 yen (about 12 quid), superb.
