Cool review about DA food:
"The Tongue Tying Lemon Squash definitely left us making a puckering face. The "tongue tying" in the name is dead-on. The actual Gillywater is a lot like flavored water, with extras on the flavor. It's like a sucker punch of lemon right at the end. It was the color of lemonade, but so not like lemonade.
The Otter's Fizzy Orange Juice is like slightly carbonated, slightly watered-down orange soda with a rim of cinnamon and sugar and a fresh orange slice. It was refreshing. While we thought the cinnamon would be overwhelming, it was just a light dusting. This was a popular drink, according to the helpful staff.
Last but not least, the Fishy Green Ale. This was, by far, the most adventurous drink there. A lot of journalists in line with us declined. The Diagon Alley team member dressed in his robes and hat grinned ear to ear as he described the "fish eggs" that release a sweet, tart explosion. The drink was a light sky blue with blueberry-something -- best described as exploding Boba Tea bubbles, but better! -- at the bottom.
With every sip from the Fishy Green Ale comes a fish egg or two. It's an odd sensation because it's a delicate little bubble or fruit, or something. No chewing involved. It bursts right away and the tarty flavor one would experience from a Sweet Tart explodes in liquid fashion. Highly recommended if you can get past the name and the Diagon Alley team members' description of it."
