Saryo Cafe is located just right in front of Konjiki Ramen. The space is small and people waiting for ramen will probably end up watching you eat your soft serve, but it's well worth it. There are around 8-9 seats available in the small space and staff are always very polite and friendly. They specialize in matcha and hojicha soft serve but they also have a variety of other cakes as well. The hojicha soft serve and sundae are my all time favourites! I've also tried the Uji matcha brown and it was delicious as well.
Definitely a favourite in the neighbourhood, I know I will be back for more in the spring/summer.
