Great range of bakery needs out in the East.
I go here regularly for bread flours, yeast, butter, pizza bases, dried fruits and nuts, eggs and all sorts (cheaper than the supermarket in most cases). The staff are also knowledgeable in helping you find what you need.
Aside from grocery, they also stock a wide range of cookware, pastry cases, icing tools and much more.
If that wasn't enough, they are open pretty late, so of you forgot something when you start baking they are open for business.
