Cafe Topinambour is in a beautifully maintained, old-style Japanese house about a 7 minute walk from Kunitachi Station. You have the option of sitting in a Western-style or a tatami room for your meal, depending on what's available. Extensive selection of daily specials and desserts. I got the tofu quiche and my friend got the Japanese set, both of which were delicious. We sat in front of the big windows looking out onto the porch and the perfectly manicured Japanese garden. Very reasonably priced for what you got and didn't take long (maybe 30 minutes) to get our lunch despite the house being full. Took about 45 minutes to reach the restaurant from Central Tokyo but I would make the trip again in a heartbeat.
Cons: Distance from the city
