...like Marugo in Akihabara about which I wrote some time ago but Tonkatsu Sugita (とんかつすぎ田) in our neighborhood has a bright future (although it isn't that new: it's been around since 1977) : its tonkatsu (here in the standard, rosu-katsu as well as in the fillet/hire-katsu cut -we always order them this way so we can try both) are among the best I have eaten. And it seems it has started making a name because with time, we see more and more people waiting outside (as you can see in the pictures, these restaurants are, as a rule, very small).
I just found out that Sugita *did* get its mention in the Michelin Gourmet Guide for places under 5,000 yen last year. Which goes to show that you can't keep a good restaurant down.
