My daughter and I were lucky enough to experience Diagon Alley yesterday. We were both super impressed. The area is detailed, authentic and beautiful! We enjoyed the Gilley Water, had a delicious lunch at the Leaky Caldron and had ice cream. Butter beer ice cream is delicious. My daughter had a great time with the interactive wands. The 3 Brothers show is also really good.
All in All... it was amazing and I see us spending lots of time in this area!!
