First time visiting this Katsuni, and both of us agreed that the person that helped us was very knowledgeable and helpful when it came to the dietary requirements of both of us. The lady made sure the food had no onion or garlic and for my better half, no gluten. Even treated the preparation to avoid cross contamination and requested staff to use different utensils (not needed but attention to detail was cool). The food itself was very well prepared and very generous servings. Ramen was very good, however the long trip home made the noodles a bit more than al dente which was unavoidable.
Would I recommend Katsuni Silverdale? For the service we got and the food we received, yes.
