Their vanilla macaron was the best thing I ate in Vegas (which included Wynn Buffet, Aloha Kitchen, BLT, rm Seafood) $3.50 isn't so bad because they're larger than most macarons I've seen. They sell a 5 pack with all of their macaron flavors for $16.50.
The carrot cake cookie sandwich ($3.50) was very big and I liked how it didn't have raisins. No complaints.
I'd stay away from their red velvet cupcakes. They have a strange filling and the cake had too much cocoa. Tasted more like a chocolate cupcake more than anything.
