For some reason I thought that I've already wrote a review for this place because I've been going here for years! I literally stumbled into this place by accident. We were actually looking for an Italian restaurant, and close by was more of a pizza place, not so much pasta.
Tonkatsu Kiyoshi is definitely a hidden gem. It is next to the Euphoria Wellness dispensary. It is a small family owned restaurant. They have bar style seating along with normal restaurant seating. They have a specials board and a normal menu. Their menu ranges from $5-$18.
They literally have the best katsu in Las Vegas that I've tried so far. Depending on how I am feeling I either get the Chicken katsu or one of the tonkatsu. It's a hefty serving! It comes with rice and salad. The salad is just shredded cabbage but whatever the dressing is made out of is the best! It pairs well with the katsu! You also get a side of miso soup and a little pickled shallots. Everything is so good. You also get to make your sauce with the tonkatsu sauce and crushed sesame seeds.
The tonkatsu donburi is my second favorite. When I order food to go or for pick up, I always get the donburi mostly because if I ordered the normal katsu, it might get soggy. The Donburi is really good! It also comes with the miso soup. Make sure you try it out!
The melon soda float makes for a drink/dessert. Just saying!
Oh and the service is great!!!
