Stopped by when I was in SF only a couple minutes walk from BART and ordering online was super…read moreconvenient since their website accepts Apple Pay. I ordered the vegetarian curry with tofu and broccoli at the medium spice level (~$17). The spice level was exactly as described and the curry itself was flavorful. My only small complaint is that I wish the vegetarian curry came with a wider variety of vegetables. I was surprised it didn't include potatoes which were an additional charge. The portion size felt fair for one person I had enough to have leftovers for dinner. I do wish the price was a little lower since it's a takeout-only spot, but considering the area, it seems pretty in line with what you'd expect to pay in downtown SF. My partner ordered the chicken katsu curry and really enjoyed it as well. Definitely worth checking out.

Overall, it was an alright spot for a quick lunch. The Japanese curry was decent--nothing…read moreparticularly memorable, but it hit the spot if you're looking for something simple and filling. A curry katsu dish cost $20 before tips. One downside was the customer service. The woman working the counter came across as unfriendly and didn't seem very welcoming, which made the experience less enjoyable. Also, keep in mind that this is strictly a grab-and-go place. There's no seating available, so you'll need to plan on taking your food elsewhere. If you're just looking for a convenient curry lunch, it's fine, but don't expect much in terms of service or dine-in atmosphere.

There's a plethora of indoor and outdoor seating, and we opted to sit outdoors since the weather was particularly nice on that day.

This blew me out of the water. It was not too sweet, not too mayo-y, and something about the bread was even better than milk bread in Japan. It was slightly chewier and heartier while still being super soft, and had an indescribable taste - like butter? The green tea lemonade was unfortunately short of the matcha/lemonade flavor. I'll have to come back to try their protein bowls and curry when I have more time Logistics: - indoor and outdoor seating - extremely limited street parking nearby, but walkable from light rail, Caltrain, buses, bike trail - if you order takeout step back outside and they'll hand it through the window

All good... $17 Tonkatsu Curry...the plate was huge! A thick, wide, juicy, tender, pork cutlet with that signature Japanese crispy crunchy batter embracing each other like a romantic couple on their 3rd date.

I do see that the curry is prepared different from other curry restaurants and the curry itself is actually very good. Rice to curry ratio is like 80% rice, 20% curry. CHICKEN KATSU CURRY (3.5/5) - chicken is super thin and I wish there was more. EBI FRY CURRY (4/5) - decent, crispy ebi. I actually enjoyed the panko breading and it went well with the curry. Overall, nice casual spot. I can see why it's popular with locals but I wouldn't go out of my way for this place especially with the likes of Curry Hyuga.

Everything was made fresh to order which was nice, the hamburg steak takes extra time. The curry itself was good, good ratio of rice to curry as well. You can pick spicy or not spicy you want the curry. We got +2 spicy which was fine for us - but if you don't handle spice well it might be considered spicy. The tonkotsu was good portion size, crispy but was a little dry. However, the curry helped with it. For the hamburg steak, it is a beef patty with cheese in it covered in a brown sauce. The brown sauce was a mix of sweet and savory. It came on the side with curry rice. Good portion size. Overall, will be back again to try their other dishes. They have ones that I have never tried before and I saw others ordering different items like mapo tofu curry rice, curry udon, and so forth.

I'm happy that even after coming here for almost 20 years that very little has changed. It still tastes the same, the prices really haven't changed much, and the place still looks and feels the same. The only major change is that they charge for the pickled daikon (I think it's daikon, but I'm not totally sure). They used to just give you a small amount, but now if you pay for it they give you a good portion of them! My go-to here has always been the Chicken Katsu over Japanese curry, medium spicy, with zucchini, eggplant and sausage if they have it. It's still an excellent plate and the Japanese curry is rich and delicious. I love this place and I hope it continues to be here for many more years!

The potato salad is also yummy. The chicken katsu didn't wow me which was surprising since I've heard people rave about it. It seemed like standard katsu to me, though the portion is huge and the noodles are nice and bouncy. Also very affordable price point for the portion size. Lots of seating inside at this location and they are open pretty late.

Tempura 5/5 Probably the best and lightest tempura I've in the states. Comes close to being in Japan! Overall, definitely will be back when I'm craving tempura or katsu.

The food took some time, even though we were the only party at the time that we ordered, but you can tell that it is made of fresh and with love. As someone who enjoys eating flavorful meals, but is also very conscious of healthy choices, I was very grateful that they had grilled chicken curry option since it normally comes fried only, and that you could opt for brown rice instead of white rice. My chicken curry dish was so hearty and flavorful, the curry is housemade and the chicken was very tender We also ordered a chicken Katsu Bento, which was both juicy yet perfectly crisp. It comes with a little bite of soba noodles and a bite of macaroni and that small salad . Order at the counter , and there's a handful of indoor tables The tonkotsu ramen was also delicious - came with two super huge slabs of juicy pork belly and the broth was scrumptiously rich .

Personally, I wouldn't be craving this later, but I would go back if I was in the area and hungry. I also found that this curry is more along the lines of American spicy versus Japanese spicy. I don't handle spice well, but usually a hot Japanese curry is barely spicy. However, here the mild was in a very comfortable zone while the medium was bordering on too spicy.
