Hey everybody!!!
You do mention some great shops but there are a few very special shops and the quality of their products are top notch. Here is a short list...
Amnesia- ask Sissi to suggest, she is the owner.
La tertulia-most people can walk by and never know it is a coffeeshop!
Popeye-Most people pass on the way to being crammed into Barney's (Barney's IS awesome, though)
Mellow Yellow-The Amsterdam original
