It took me awhile to finally visit Duke's Grocery, as a Brit I was skeptical of it's authenticity. I thought to myself, what do two guys from America know about British food, let alone enough to open up their own London cafe? A lot as it seems. I paid my first visit on a Sunday morning, all I really knew of Duke's was that it has a rotating sandwich menu which is updated daily on its Facebook page. A few hours before my visit I took a gander at their Facebook page to see what was in store for me, that days menu hadn't been posted when I checked so all I was expecting from past menus were sandwiches with interesting names, certainly not something you'd find in your typical English cafe.
