I was looking for a ramen place after a morning of shopping and saw that this place was rated very…read morehighly on Yelp and Google. Interior is very nicely decorated and it was a little bit busy around 2 PM on a Monday. The service was very fast though. I got the miso buta tama ramen and it was average. The noodles had a good texture. The soup broth was overly salty and I was so thirsty after my meal. The vegetable was also slightly undercooked. Sadly, not a very authentic ramen spot I think I would categorize it more of a fusion spot. I'd be open to trying other ramen spots around but won't come back to this place.

In fact, this was one of our least appetizing meals of any type over 4 weeks of travel. Some of the worst ramen of any restaurant I've ever tried. The fried rice was not much better. With all the great restaurants in Barcelona, there is no reason to eat here. Noodles were not ramen noodles by any stretch of the imagination. More like pasta masquerading as ramen. The broth was thin and disappointing. The tonkatsu was not crispy but was limp and oily.

It had all the crunchy veggies and texture going on. The rice was a bit warm but cooked well. I would definitely order this again! Agedashi tofu was crispy and light in a fragrant broth.

Menu is large, full of the foofoo shishi rolls. Cool, clean, modern restaurant in the heart of Gracia. It's good!

On the way there I see Onaji and it was open. I thought maybe it closed down because I haven't seen any recent reviews. Yes they are still in business. I got the beef bibimbop. The Korean gochujang paste that comes with it is a little salty so just put in a little and a time. The dish was really tasty. The kimchi was surprisingly good as well. My daughter got the bulgogi and it was a bit salty for our taste. Maybe it's just us but I find that the food in Spain is a bit saltier. The price was decent for the amount of food you get. The restaurant itself was very nice and had open seating outside. When we were there, there was only one server. He was very nice! They also serve Japanese food like sushi, tempura yaki udon. We didn't try it but I saw that a lot of people ordered it. Definitely check this place out!

Initially I thought it was a basque restaurant and to my surprise, my friend surprised me with a Japanese night of delicacies. I am not that inclined to have dinner so late anymore since I don't live in Spain, but is so nice to see places like this open until super late. Very nice decor with original tiles on the floor and mellow atmosphere. Delicious food.

I arrived for a late lunch (according to American standards, of course, as it was probably perfect timing for the rest of the Spaniards in the restaurant) and was quickly seated. I had gotten my filling of tapas during my stay in Barcelona and needed a bit of palate cleanser with a hearty, flavorful bao filled with meat -- a bit like an Asian taco, if you will. I stood firm in my order despite it feeling like heresy as "ramen" is in the name of the restaurant and a quick look around me revealed that most of the tables were definitely enjoying their ramen. Still, with things like pad thai and kimchi on the menu, I felt like I had permission to indulge in my cravings. I dug into a starter of some chicken karaage (Japanese fried chicken) that came with some homemade teriyaki sauce on the side. The chicken was perfectly crispy and the teriyaki sauce complemented its flavor instead of being too overwhelming. But the order did seem a bit on the pricier side at €7.50, which is basically the same price as one of the baos, so I think I would've ordered an extra one instead. As for the baos, I got three: the pork, the chicken, and the shrimp. They all tasted very similar to each other -- the pickled cucumber and carrot on the pork and the sauces on the shrimp did most of the heavy lifting, so I barely tasted the difference in meat. There are other places that ofter this bao delicacy in Barcelona (my reco would be Boa Bao) so come to Koku Kitchen for the ramen and gyoza instead. I did appreciate the decor of the place, especially the flower placed in a brown apothecary-esque bottle and the dim, hip vibes of the bathroom.

Last night here Barcelona we decided to try something different.. Lots of ramen place here so I…read moredecided to try one. Well I was curious to see how good or bad ramen place would be in Spain. Well curiosity killed the cat and my wallet for wasting my money . Restaurant was packed. I thought we would wait but was asked to follow one of the staff. Went downstairs and saw another dining room which was cool. Also packed with people so I was little excited to taste the food. Ordered angry chicken bao.. Don't know why it was angry because it wasn't spicy at all. Took a bite and was trying to figure out what the sauce was.. Little taste of peanut. Bao was alright but not worth the money for how much it cost for one. Then got the pork gyoza. Not bad, not much flavor but wasn't horrible. Then the main dish I ordered spicy miso ramen and pad Thai.. Why I ordered pad Thai at Japanese restaurant in Spain? I have no idea. Presentation of ramen was good. Tasted the broth and I was confused because it tasted sweet and lacked in miso flavor and no spice what so ever. Ramen was cooked little al dente. Employee was nice enough to offer chilli.. So added about 4 spoonful and tasted little better. Over all the ramen was pure disappointment, probably the worst ramen I ate at a restaurant. Then the pad Thai.. Tiny little bowl only with shrimp cut in half on top. I thought I was disappointed with ramen but man... This dish was utter failure.. No way anything near pad Thai flavor. It tasted like egg fried noodle with shrimp on top. It lacked in so much flavor. So dinner was pretty sad.. I could not recommend this place to anyone.. And holy smoke 5.50 for side of kimchee.. What the heck.. Can't wait to tell my mom how much they were charging for side of kimchee...
