Mr. Katsu

This sandwich place is definitely one of the best in OC. I love their pesto habanero sandwich and haven't even bothered trying anything else because it's just that good. There might be other great options on the menu, but I can't bring myself to order anything else. It gets my coveted stamp of approval.

This is not a take on the food because I have not tried. I came in here into this place ready to eat some food, but I was very thirsty so I asked to the older gentleman whom I assume is the owner if I can please have a cup of water. He said no, then I asked again.. because I thought maybe he wasn’t understanding me and frankly I was quite surprised that he wouldn’t. He then said no again and it was for customers only. I said no problem, and I walked out. First, isn’t it illegal for restaurants to refuse free tap water? Please correct me if I’m wrong. I doubt it. Second, are you that cheap that you can’t give a small cup of tap water? It just really rubbed me the wrong way, I’ve never been to any restaurant or establishment that doesn’t give you some water when you ask for it. He had the tiny little plastic cups right there. Anyway that’s my take, I just didn’t feel any human decency and for that I won’t ever eat here.

Good sandwiches for a quick lunch or outdoor picnic. We got the habanero pesto and chipotle Asiago and I was happy with the additional kick of spice in both. The katsu is solid and juicy. I did find myself tiring of the taste after a while, maybe because the sandwiches are pretty hefty. Saved half for later and baked it in the oven. I wouldn’t say these keep that well, but it was still okay tasting the next day. The potato puffs are good too, nice and crispy. I liked the curry ones a lot. Agree with other reviewers that it doesn’t exactly pair with the sandwiches. Perhaps a cool, more tangy side would work better?
