Ahhh, this was a tough one! The first time I had it, and waited in line for 30 minutes it was awesome and totally worth the wait!
The second time I had it was a shorter wait, still really good, but not great.
This last time I went there was no wait, and we both agreed it was just "okay".
I'm not sure if they are going down hill, the novelty for us wore off, or it is inconsistent and the last few times were just on bad days. It's a bummer, and I'm not sure with all the other choices I am going to chance it again!
