Dinner at Tonsui ( Reasonable set menu restaurant in Shimokitazawa ).
Samma ( Saury ) is broiled with sprinkled salt.
Steamed white rice, pickled cabbage and miso soup ( cabbage and tofu).
Simple, healthy, light menu and also reasonable.
The chef of this restaurant is probably early 60's ? He and his wife are always friendly and nice. 680 yen for this set menu is also quite reasonable. I 've been busy with cleaning my place toward new year. This kind of place is precious for this busy time.
