Came in skeptical and left a believer. The broth alone is worth the trip. Generous portion of noodles — I did not run out before the broth. A hearty, large bowl that is well worth the price. Service was fast even though it was packed.

Honestly one of the best bowls of ramen I have had in a long time. Noodles were springy and cooked exactly to that ideal firmness. A hearty, large bowl that is well worth the price. Service was fast even though it was packed.

Service was friendly but the bowl itself was just average. The noodles had a perfect chew and held up well in the broth. Massive serving — bring your appetite, you will need it. The chashu was tender and melted in my mouth.

Decent flavor overall. It hit the spot on a cold day. Generous portion of noodles — I did not run out before the broth. Bowl was a good size, just right for a satisfying lunch. The nori and scallions really rounded out the bowl. Clean spot with a welcoming vibe.

A reliable spot when you are craving a warm bowl of noodles. Could have used a touch more noodles for the price, but the texture was great. A hearty, large bowl that is well worth the price. Service was fast even though it was packed.

Absolutely delicious from the first bite to the last drop of broth. The noodles had a perfect chew and held up well in the broth. Massive serving — bring your appetite, you will need it. Fresh toppings and a beautifully marinated egg.
