When you walk into the store it smells like cake even though they don't actually sell cakes here.
There are tons of different decorations for every imaginable celebration, most under a dollar a piece. There are tons of different types of candles, and uniquely shaped cookie cutters.
I also come there to get bottles of their emulsion flavors for my baked goods (try the red velvet to intensify the flavor of your cake). This place is one of a kind and I always end up here when I'm baking for a special occasion.
