Like Jennasis, I was there last week Fri. 5/7. Walked over from SSR. Got in line ~9am. Was maybe group 6 or 7 in line. They opened 10 min early at 9:50am. I was out around 10am. Got the coffee cake, pistachio, and cookies and cream. I found the cookies OK. I think part of the hype is waiting in line & being inside Gideon's with the cool theming/design. (And, admittedly, following their social media.) The cookies themselves were OK... the toppings are fantastical (similar concept at Everglazed), but the end product was eh. Still glad I tried it, but I wouldn't go out of my way or take away a park day to experience Gideon's. I think there are better desserts in Disney Springs like the pastries at Amorette's or even a Sprinkle cupcake. But I realize that this is my humble opinion.
I'm a huge fan of Levain Bakery in NYC. They were the OG pile of cookie dough in a super round, big shape. I like Levain's better.
