Such coincidence! I also love Chano-ma in Nakameguro! I think the atmosphere is especially nice during the daytime (natural light) and when it is not very crowded. I often take friends there when they visit me from abroad. I wish I knew more places like it.
I have been to the large Chano-ma at Aka-renga Koen in Yokohama several times. Although it is nice, it doesn't have the charm and coziness of Nakameguro's Chano-ma. It also has too many tables and not enough 'beds!'
I hope to find more places like Nakameguro Chano-ma!
