I just visited The Sweet Tooth Fairy for the first time this morning. It is absolutely adorable - the inside reminds me of something I'd see on Main Street at Disneyland (this is a good thing). I tried the cake bites - they were so delicious! Very rich, but excellent.
**Update**
We recently returned as we were having a party and needed some treats for our guests. We were unaware of the 2 day notice for the Twix bars and cake bites, but the baker kindly accommodated our short notice (which was the next day). Excellent customer service.
It's hard to say anything negative about this place but if I were to point out the less than perfect, I'd say it's a bit highly priced but obviously not weren't bad enough to keep me away after my first visit.
