I've read reviews about Tonkatsu Yamabe prior to our trip to Tokyo but it was purely by chance that we got to dine at the Ueno branch.
We just came from Ueno Park to see the sakura blossoms and we're looking for a nice place to have brunch. Alas, we're too early because most of the restaurants opens at 11AM. We did plan to dine at Sushizanmai but since it was still closed, we decided to go around Ameyoko market first to check shoes, bags, etc. Then my daughter was checking Google map and mentioned that the tonkatsu place that I have on my list is just nearby so we walked there to check the restaurant. It was still closed but there's only four diners in line. Hmmm.. what do you think happened next? It was 15 minutes before 11AM.
