Turns out it's a cool new coffee shop for Durban (Yay!) called Monroes. It's an awesome little spot with a really cool aesthetic and vibe inside, free wifi, friendly owner, and what looked like lots of yummy goodies - and, of course, good coffee. Take a look...
"Monroes Coffee Shop is a quaint artsy style café providing the perfect mix of vintage decor, photography, home style coffee bar/deli food and of course a great cup of coffee."
You can find Monroes at 350 Gale Street (opposite The Factory Cafe, inside a signage and printing company). They're open Monday to Friday, 8:30am to 4:30pm. I didn't sit down to sample their stuff last time, but I hope to do so very soon! Let me know if you'd like to join me :)
UPDATE: On a recent visit I noticed some big changes and it seems the management has changed, as well as the decor, menu offerings and service. No longer worth a visit, I'm afraid.
