  Such a wonderful experience! All
  You can eat ramen, sushi, appetizers, hibachi, fried rice! All the food was delicious these photos don’t ever cover a majority of the food we ate! The service was friendly, quick and overall nice! We were not prepared for how much came in an order of food so beware! It’s not just one piece of the item it’s a whole serving! It’s a little pricey but worth the quality and quantity of food you get! Everything is made to order and will not disappoint!

  Great restaurant with good food! It’s a fun atmosphere inside as well. They have lunch specials and all you can eat sushi for a very reasonable price. I recommend the tonkotsu pork ramen!

  ⭐⭐⭐⭐⭐
  KOI Ramen and Sushi
  
  We’ve been watching this team pour months of care, craftsmanship, and detail into building out their restaurant, and the anticipation was real - and they absolutely delivered.
  
  The food is incredible. While there are only a handful of gluten-free and dairy-free options, they are extremely accommodating, knowledgeable, and careful. Every allergy-friendly dish we had was outstanding. Our non-allergy family members have also loved everything they’ve ordered - which says a lot.
  
  They also offer an all-you-can-eat buffet during dinner on weekdays from 4 PM to close, which has been a huge hit and definitely adds to the excitement and crowds.
  
  The staff is professional, kind, and clearly working their tails off. We are genuinely lucky to have a place like this in our community.
  
  Helpful tips for fellow diners:
  • They are brand new and already packed - please be patient and gentle as they find their rhythm.
  • Dinner lines can get long because they’ve been slammed from day one.
  • The team is constantly moving at full speed trying to keep up.
  • There are two restrooms, so restroom lines can form during peak hours.
  • Parking is good and not an issue.
  
  We’re so excited to watch this place continue to grow and settle in. It’s already something special. 🍜🍣✨
