Came here back in April. I was pleasantly surprised that there wasn't any customers besides us and one other table. I thought Tonkatsu Kiyoshi is pretty legit.
We had two appetizers. The karaage and the gyoza. The karaage was okay. I've had better but the chicken was still quite juicy. I really like the gyoza though. Might be because of the sauce. The soy sauce had some yuzu flavor to it which really brought out the gyoza. Not to mention that the gyoza had a light skin and a good stuffing.
I had the tonkatsu pork and shrimp. You are given all the sauce ingredients like the sesame and the grinder on the table. Personally, part of the fun is to be able to grind the sesame itself and I always feel like it makes it legit when you have the sesame seeds to grind for Tonkatsu places. With that said, it was a big portion for a good pricing. You are given two pork(that are already cut for you) and 2 big shrimps. I personally thought the shrimp was really good, might be even better than the pork in fact. They fried it to perfection with the panko and it was the perfect proportion of the skin and the big fat shrimp.
Service was pretty good. The server actually had a mishap with our order and she gave us the appetizer as an apology.
