TLDR: they have a lot of very unique "for the gram" icecreams. Is it worth it? I don't know.
I used to work in an ice-cream store, so as you can imagine, I've eaten a lot of different ice-cream and enjoy doing so.
I chose the charcoal soft serve on a regular cone.
It was my first time having this flavour of ice-cream. And I recently had charcoal for the first time in the form of a cream puff from a grocery store. The charcoal ice-cream had tasted the same as the dark, enchanting cream puff: plain. Like nothing... Pretty disappointing. I found that the icecream wasn't even that sweet (which I guess is a good thing?) and the charcoal provided a grainy texture as the charcoal powder was kinda chunky. The flavour was like 1% milk if anything. Due to the lack of creaminess, it melted very quickly as it didn't hold as well as a regular vanilla soft serve.
I thought that the regular cone was pretty and unique, but not as functional as the traditional cake cone with a grid at the bottom. My cone leaked within 1 minute of receiving my ice-cream and no, there was no hole or breakage. The point at the thin cone just collected the quickly melting ice-cream :)
Overall, I feel like this treat is something one would only get for aesthetics or something to try once. Definitely not something someone would choose because they actually like the flavour.
I wanted to try the gold foil cone but found it a bit expensive.
Apparently this place also serves a lot of different flavoured Boba that comes in their bubble tea or SUNDAE! I think this is another unique thing they do and one that is for "the gram" as it isn't common and I haven't seen before.
