Potato katsu...where can I find?
I was in Seattle recently and had potato katsu for the first time at a sushi place. They were so good I want to find some in Boston? I live in Allston but will happily travel to get some.
Potato katsu seems to just be korokke, or croquettes with no filling. They sell them at Ittyo, or at least they did when I went some time ago (I read it's changed a lot) though they might have had carrot in the mix, too. Tampopo has filled ones. The best is the curry. I don't think they have plain ones.
The Japonaise bakery has a croquette sandwich which is what you're looking for. There's one on Beacon Street in Brookline. It at the first stop above ground stop on the C line.
