★★★☆☆ 3.0 steveinoakland · Nov 2025

Got ramen to go and when I got home realized for $20 they gave me maybe 8oz of soup. A 2/3 full small half size container. When I get Pho to go I usually get a full tall container of soup plus the ingredients in a separate container. Called and asked and was told this is what owner instructs them to give and she can’t be contacted. Felt ripped off. It’s not like soup stock is expensive and now I have a tiny amount of soup for $20. Used to eat here all the time and it was expensive but portions were appropriate and loved it. This time was 2 stars so giving above my feelings due to prior good soup but not coming back.

Tried them for the first time and after I was done eating I passed out in my chair. Ramen was so comforting it put me to sleep. They were also really nice even though I came in close to closing time!

This place is fully automated with a kiosk and no human interaction, which bothers me to start. My biggest gripe is when I pay for extra protein, I expect extra protein. Don't be cheap and collect people's money and rip them off giving them the same amount of protein on the normal order. Other than that, this location is CHEAP CHEAP CHEAP, they skimp on toppings compared to other locations and like I said above straight up rip you off when you order extras by not giving them to you. Will not come here again.

I recently visited this ramen spot and was thoroughly impressed! The atmosphere is warm and inviting, making it a great place to relax. The service was top-notch—friendly and attentive throughout the meal. We got black garlic noodle, rose tteokbokki and bibimbap. They were all delicioso. Highly recommend for a tasty and friendly dining experience!

I got a few items of food, as it being my first time trying this type of food as well as this establishment, I really appreciate the help that the nice waitress have us. She was so full of energy and made the atmosphere brighten up. Over all we ate all we could, didn't finish all the food but then again we all got a plate and side per a person. All of which came out to about less than $20usd per a person including some type of drink.
