jib71 - LapGirl has been drooling over the Tabelog photos of the Soraben Kobo. MrLapLap was concerned that the bento with lots of ikura might be more vinegary than she'd expect, but she's certainly up for giving it a go. It certainly the kind of food that appeals to her and that she rarely has in the UK.

bocastephen - getting to the Ekiben shops at 7am from the Takanawa entrance at Shinagawa with our bags before boarding the train to HND is too risky. Someone is going to wind up feeling stressed. Odds of this venture not making someone angry or irritated will be better if our luggage has been checked in. High likelihood that nobody will have had breakfast.
