I went on a journey today that was supposed to take me to the National Zoo. Unfortunately I forgot about the National Zoo being a Government organization. It is currently shutdown. So my journey took me in a different direction. Fortunately, I ended up at the The Spice & Tea Exchange of Georgetown.

The proprietor was very pleasant and encourages you to open the jars. This I did and I purchased Herbes de Provence and Ginger Sugar. The Herbes de Provence is excellent and I am sure the Ginger Sugar will be also.
The shop sells spices, herbs, sugars, salts, peppers, and teas.
