On the Grid : Kalustyan's
"While not a destination for its interior design, Kalustyan's will blow you away with it's wall-to-wall selection of hard-to-find spices and ingredients. From Asian to Indian to Middle Eastern to African— ethnic restaurants around the country order their spices from here. If your local grocery store is giving you blank stares when you ask them for sumac, it's time to try Kalustyan's." - Marcelo Cardoso
