I initially thought this would be a gimmick...Same ice cream taste but just in a different form.
However...it was pretty amazing. I got the earl grey flavour expecting it to barely taste like earl grey but the tea taste was definitely there. Also tried the milk tea flavour and was not disappointed. It was fresh and the texture is unlike regular Ice cream-it's much better!
The longest I waited in line was for 30 mins and totally worth it. It is a bit pricey ($7.30) but I suppose you're paying for the gimmicky part and the quality.
Definitely give this a try if you're in the area.
