It's cash only. Service was quick and nice. The ramen itself was good, but nothing out of the ordinary. The egg yolks were slightly soft/raw which is perfect for me.
We ordered the house tonkatsu and the katsu curry. The curry broth was good and I liked how they serve the katsu on the side, to keep it crispy.
The house tonkatsu only comes with 2 small slices of pork. The extra meat is a bit pricey for what you get (I think it's $3 for 2 pieces? Definitely not worth it). But the broth was good and not overly salty (the "house" tonkatsu is less salty than the regular tonkatsu, but both are still pretty salty)
Would I come back? Probably not, there's other better ramen places in the GTA in my opinion.
