Not to steal Magritte's idea, but:
This is not roast chicken.
I first saw RinRinSaiKan on one of those awesome 'hey, lets-explore-Tokyo's-shitamachi' TV programmes, and was kicking myself because I only caught the last two kanji of the closest train station. I searched every combination possible, but was stumped. Then, by some miracle, as I was going home after the epic day of sumo, I noticed that the station I had just entered was the same one from the TV programme! Coincidence or what? I guess the veggie gods were smiling down on me.
Walking around soon became an impossibility, due to the strong, cold wind, and so we took refuge at Sumida Coffee, another hidden gem. A basic, retro interior with a good heater (very important!), really, really good coffee and a quiet atmosphere make it a lovely place to chat for an hour or two. The glass coffee cups are handmade in the area, and remind me of the Bohemian glass of my childhood.
