Came here yesterday after a beautiful afternoon walk downtown. Line up was pretty long but I expected as much given the location and the hype.
Pros: Staff are very friendly and efficient, portion sizes are huge and price in comparison to what you get is quite reasonable in my opinion.
Cons: Although the presentation is very impressive, I didn't find as much flavour impact with the toppings as I might have thought. I ordered the Bangin Brownie which was chocolate soft serve and a combination of brownies (they were good), rolled in crushed cookies (these were okay).
I'd come back again and try more - would like to try the soft serve on its own too.
