As a cupcake baker, I can be very harsh when judging how good a cupcake is, but this place is AMAZING!!! I recently tried Georgetown Cupcake in Soho, and if Vanilla Pastry Studio was located next door, they could run Georgetown out of business.
The shop is very cute and aesthetically pleasing. The cupcakes were $2.50/each, which I believe is very reasonable for the high quality product that you will receive. Their chocolate cupcakes are particularly amazing. It's very easy to make chocolate cake too dry or too dense, but the chocolate cupcakes at Vanilla are light and fluffy.
I highly recommend this bakery, and based on the quality of product that I tried, I believe they would do a great job of baking cupcakes for a wedding or other event.
