    Tonkotsu Black
    Kathy W.

    This is a small ramen storefront in a big shopping center on Harbor. Although I've been there several times for lunch, I've never had to wait for a table, even though there are only a handful of tables in the restaurant. There are many ramen options, plus traditional add-ons, as well as a number of side dishes. I've enjoyed both the tonkatsu miso ramen and the tonkatsu black ramen -- both had flavorful, rich broth, tender pork, and fresh vegetables. The takoyaki were tasty nuggets of octopus -- but the fried baby octopus were even better. If you're going for octopus, go for it! Service was quick and efficient and there were a lot of fellow patrons clearly on their lunch break, too.

    This is a hidden little ramen spot in a shopping center in Fullerton. It's tiny but the food is decent. The service was quick. I got the chicken ramen and it was super filling. I'd say it was average as far as ramen goes. While it was decent, my chicken was a tad bit dry.

    Wanted some ramen and curry so we stopped in. It was nice to have a simple and concise menu that still offered a good variety. Husband got the Tonkotsu Spicy Miso and I got the Tonkotsu Miso + Level 2 spicy, and we shared the larger curry bowl (my ramen had a spicier kick whereas my husband's had a warmer overall heat to it). Everything was super tasty and I particularly enjoyed the slight noodle chew from the perfectly cooked noodles. Service was quick and attentive. Appreciated there wasn't too much small talk and we got straight to the food. Smaller spot so it may get busy quickly. Worth the wait. For sure we will be back.

    The food was absolutely amazing! I devoured every bite, and it left me craving more. The service was quick and efficient. Though the store is on the smaller side. The ambiance reminds me of ramen shops in Japan. It's definitely a spot worth trying if you get the chance!

    Came here on a whim to eat ramen late night and we were pleas surprised w the quality and flavor! My party of four opted to get the ramen combo, which came with an appetizer for $5 extra. We got one of each appetizer and they were all delicious! The favorite was the Squid Karagge and everything was pretty crispy. The tonkatsu miso ramen had pretty solid and bold flavor and we appreciated that it came with half an egg, although a full egg would be nice as well. I loved the corn topping and felt the bowl came together nicely. Service was quick for it just being one guy working. Major props to getting our food out at a good time but still being delicious. Ambiance is clean, I've seen this ramen place driving by but never actually stopped to dine here. So glad to have done so though and we will definitely be coming back!

    Stopped by this spot for Japan. Clean, bright fast service atmosphere. Efficient (if quick and quiet) service. Tonkotsu ramen was tasty.

    Good service and food in this small Japanese restaurant. Ordered the tonkotsu black ramen and okonomi yaki.

    Nothing beats ramen for cold weather eats. I'm also excited to find another ramen spot w curry katsu! I wasn't hungry enough for both. But I'll definitely be back to give the curry a try. It's a small spot but conveniently located near a boba place. I need a milk tea w my spicy ramen. They were kind enough to put the spice on the side so I could spice it to my liking. My friend added spinach on the side and also got the shrimp tempura. The tempura was funny looking to me cuz it was all squared off on the edges so I'm not sure how/why they do that. But I wish they had tempura dipping sauce w it instead of what looked like maybe a spicy mayo. I took home my leftovers in separate containers for broth and noodles and enjoyed my leftovers the next day. It was just as yummy if not more so because the spice settled into the ramen. I recommend this unassuming ramen spot for after a day of shopping at all the nearby retailers - target, Costco, Tilly's, and so much more.

    The ramen I got was good until the broth (a major component of eating ramen) started tasting overly salty, like MSG level salty. Also, the AC was blasting in the evening and it was still wintertime when I ate here, yes this is a late review lol. It was overly freezing inside to comfortably enjoy my ramen bowl. Don't know if I'd recommend J San Ramen, as there are many other ramen spots deserving of going to instead.

    I've ordered from them on Grubhub before but this was the first time that I've been in person. I orders the tonkotsu black ramen. The ramen was good with a nice sized portion of noodles and the broth wasn't super heavy but the flavor still packed a punch. My favorite part was the char siu on top because the edges were a little bit crispy and it went perfectly with the flavor of the broth and noodles. The only major thing that I wish was that I got both halves of the soft boiled egg because it was cooked perfectly and had a nice soft centered. The shop is on the smaller size with around 10 booths give or take. The staff was friendly and got everything out in a timely manner, so I think I'll come back here when I have a ramen craving.

    I got to try the curry with combo cutlet plate and the spicy beef bowl. Both really good, I love their ginger.

    Long overdue review for one of my family's regular katsu spots in the area. We've been coming here…read morefor quite a while, and the experience has always been consistently good. The staff is always attentive, friendly, and quick with service, which makes dining with kids much easier. The katsu is crispy and cooked well every time, and it's one of my kids' favorite places to eat. Portions are solid, the food comes out fast, and the overall atmosphere is casual and family friendly. Definitely recommend for families with kids looking for a reliable and satisfying meal.

    Food: 5/5 Service: 4/5…read moreAmbiance: 4/5 Parking: 3/5 Family friendly: 3/5 Stroller friendly: 2/5 ADA accessible: 2/5 First let me say I'm not a big katsu fan, but my Godson picked out this place to eat. I think I've been converted. I don't think I've really had good authentic katsu before. The chicken lady was light, tender combined with the grounded sesame sauce? It is something you need to try if you have yet to do so. The katsu meal itself ($17.95) with the combo (+$7 which includes either kimchi udon, or soba, Tuna roll) iis big on it's own. Also, the shaved cabbage salad is a great compliment to the meal. I'll be back with the family to check out the other offerings here. One downside, the space is tight, so strollers and wheelchairs won't be a comfy fit. However, there were littles here around 7 pm for dinner. All in all, is highly recommend Yoko Donkatsu.

    Casual dining for Japanese food …read more Order either at kiosk ( left side) or at the counter. Daily specials are offered. See poster stand outside the entrance for listings. Quite a variety of food options : curry, rice bowl, tofu pockets, katsu, , chiken wings and more... Minimal tables for in dining. Great self serve soda fountain machine. Unusual flavors to choose from. Hubby and I both enjoyed the ( Monday) chicken curry lunch special which had rice, chicken curry katsu, cabbage salad, macaroni and a fountain drink. * It would be extra nice to help the staff and tidy up after your meal .

    A visit from a few days ago…read more The cashier was really nice, friendly and bright! Excellent customer service! The place is always immaculate, clean and fresh! So I ordered their chicken teriyaki bowl for $10.99 and made it keto (no carbs) with extra veggies (carrots and broccoli only). - They forgot the jalepenos - The carrot pieces were really BIG and fibrous (not enjoyable not tender); tough to chew - The chicken was 2x cooked or overcooked (kinda hard), my 1st visit they cooked it to much softer - Portion size was good A healthly meal, but not that enjoyable. I will try their bulgogi bowl next time. I wish they would sell their Cholmyun without the katsu (I can't eat fried protein foods due to health reasons).
