I went to Kinton Ramen after work on a Friday. The quality of the ramen and broth was pretty good but falls short compared to other places, such as Sansotei.
I got spicy garlic ramen with pork and an egg. The broth was creamy and the level of spice was perfect for me! The noodles, however, were a little too hard for my liking. Overall, I thought it was pretty good and I don't have any real complaints.
For an appetizer I got the Age Gyoza. The gyoza themselves were good but the sauce really made it delicious! It's almost like a spicy mayo.
Based on quality alone I'd rate the ramen and gyoza 4/5 but the price wasn't quite right. The spicy garlic ramen comes with bean sprouts and garlic. Pork/chicken is extra at $2.50. I also added an egg for another $1.50. Unfortunately, the price of the ramen ($15) is a good $5 more than Sansotei, so I wouldn't have any reason to choose Kinton over Sansotei.
Overall, Kinton offers good quality ramen and delicious gyoza! But when comparing to Sansotei, there's no competition in my opinion.
