While I would love to say that everything about Petit Four is great, I've had a couple of poor breakfast takeout experiences recently.
Their pricing on the breakfast board does not reflect what they serve - for instance, the muffins in the display case are not the same as the "4 am muffins" on the board and so are a different price.
The quality of the muffins has also gone downhill in the last couple of months. They are too sweet, dry, and too greasy compared to what used to be perfect.
With respect to lunch takeout, I find the prices pretty high but portion sizes are large. The tiny desserts are awesome!
