Their black sesame ice cream is really good! I definitely prefer that over the matcha. I feel like the matcha is a little too bitter for me, but to each their own. I have tried the swirl and it was good, but I just didn't like the matcha ice cream by itself. I just feel that the black sesame ice cream has a similar taste to black sesame dessert soup and it really has a nice sesame flavour. Both matcha and black sesame have very strong flavours. Also, I've only gotten my ice cream in cups so I can't speak for the quality of the waffle cones.
I tried the warabi mochi sundae and it was alright. Wasn't a big fan of the mochi (it was tasteless and had a jelly-like texture, which I personally did not like) but the red bean was good! The service is great and friendly! The place is really small and parking is a hassle but I've only gone during off-hours so I haven't experienced any slowness in service yet, although I do imagine that wait times can be quite long during peak hours due to the limited space.
I will be back to try other sundaes, drinks and maybe their other desserts as well! :)
