Uncle Merv's Original Shakes makes some killer smoothies, all with non-dairy milk bases.
My favourite would have to be the Macci-Porter, a delicious blend of Tahini, Dates, Cashew nuts, Banana, Honey and Soy Milk.
Grab a sarmie (sandwich) or a croissant and a coffee or smothie and plant your bum at the nice, long table under the tree to do a bit of people watching on a Sunday. Or if you're feeling tender ffrom a big party the night before, you can order a health breakfast and recover in the sun
The sidewalk shop is situated next to the Infor'motion Station in Fox Street
If you're feeling like you need the wind through your hair as you take in some city sights, then rent a bike from Uncle Merv's and free-wheel through Maboneng. When you're done, quench your thirst with a smoothie and refuel that pedal-power machine of a body with a light snack from the shop.
Book a tour with Mainstreetwalks, who will give you some great insights into the area.
Just remember to be vigilant if you choose instead to go out on your own
