Momosan Waikiki is an absolute go-to for me. The quality here is genuinely unsurpassed. As someone who appreciates a proper, scratch-made broth, I can tell they take real pride in their craft—the pork bone broth (Tonkotsu) is the real deal, incredibly rich and heavy on the collagen. I highly recommend getting the "All-Star" version, which comes loaded with all the best add-ons. I also love their Tokyo Chicken Ramen; the broth is flawlessly light, smooth, and nuanced. Beyond the ramen, the appetizers are amazing. The sticky ribs are an absolute must-order, and the popcorn shrimp is one of my all-time favorites. The hospitality is top-notch, with Jamie always taking fantastic care of us at the bar. If you go during happy hour, the deals are unbeatable for the level of quality you receive. It's essentially the exact same A-tier standard as Morimoto Asia upstairs—using the absolute finest ingredients, prepared by chefs who genuinely respect the food. The whole experience feels authentically just like being in Japan. Highly recommended!

This spot is great! While staying in for Waikiki for a few days my family came here twice (once for dinner with a local friend who recommended momoson in the first place, and again for lunch/happy hour). The standout was definitely the spicy tan tan ramen. The broth, a red curry base, was delicious and unlike any other ramen I've had anywhere in the world. The noodles were also high quality, and the pork included in the ramen bowls was tasty (and was cut kind of similar to thick cut bacon). I also tried the tonkotsu ramen which was great (not the best I've ever had, but definitely among the better bowls I've had in the US) and the dan dan noodle which was spicy and flavorful (much spicier than the spicy tan tan which I liked). For appetizers, we also tried the pork ribs (apparently the house specialty), the gyoza, and the karage. The gyoza and karage were good and definitely similar to those I've had in the past, but the spare ribs were delicious. They were extremely crispy and the meat was delicious and tender. The sauce reminded me of general Tso's chicken in a good way. So tasty! Their draft beer deals during happy hour were also great and were a much appreciated escape from the hot sun. Overall Momosan is really good and not too expensive given the location! Definitely worth a try if you're in the area and unsure about where to eat.
This place was right downstairs from our hotel and directly across from the beach, so we decided to give it a try. We honestly didn’t expect much, but it turned out to be surprisingly good. The ramen was delicious and ended up being one of my favorite meals in Waikiki. Everything was flavorful, comforting, and exactly what we needed after a day at the beach. The staff were friendly, the atmosphere was relaxed, and the location couldn’t have been more convenient. We enjoyed it so much that we kept talking about how unexpectedly good it was. Definitely worth a visit if you’re in the area.
Momosan is a great place to grab a meal after a day at the beach. Conveniently located on the beach front, its easy to access and has a fresh and inviting atmosphere. They have an excellent lanai to sit and enjoy the weather while you eat. The food is very good. The Momo set gets you a bowl of ramen and a side for 33, and the sticky ribs are absolutely incredible. Perfect mix of tender and crispy, with a delicious glaze. I even forgot to take a photo before I had finished one off. The Tonkotsu was a solid example of a staple ramen, with a rich, silky broth that didnt have any of the greasy or fattiness that some cheaper ramen end up with. Service was also great. My server Janzy was extremely pleasant, making multiple stops by the table to make sure my water stayed topped up and my table clear, but never feeling intrusive. My food was on the table within 10 minutes of ordering as well, and I was able to request the check almost as soon as I finished eating which I greatly appreciated. The restaurant photographer, Mara, was also very kind. She asked if I wanted a photo taken of my visit, and when I declined she was very polite and quickly moved on with making a fuss. My only issue was that the music outside was slightly louder than I would have preferred, but only minorly. Overall an excellent experience that I look forward to repeating!!
Visiting Momosan in Waikiki on a cool, rainy night definitely hit the spot for comfort, though the meal itself left us with mixed feelings. We found the Tonkotsu ramen to be quite heavy, and it really could have used more bean sprouts or bamboo shoots to provide some much-needed crunch and lightness. The preserved mustard greens were an interesting topping choice, but ultimately they felt a bit salty and didn't add much to the overall flavor profile. Unfortunately, the vegan miso ramen missed the mark for us as well, tasting far too salty due to a very heavy hand with the miso paste. Seaweed salad and edamame app were good though. While the atmosphere was cozy for the weather, the flavor imbalances mean we likely wouldn't choose to go back again. On a positive note, our waitress was incredibly helpful and kind, providing excellent service that made the evening much more pleasant. Even though the food didn't quite live up to our expectations, the warm hospitality was a bright spot in our dining experience. Overall, it served its purpose for a rainy evening, but there are better ramen options to explore in Honolulu.
