Since I was still full from breakfast, I only went to Peak Souk Cafe to drink a coffee.
There isn't lots of space, one big table, one smaller one and one very small one plus an outside sitting place (very small as well).
As the owner became aware that I won't eat anything, I was disapprovingly asked to sit at the very small table, since it was already lunch time (although I was the only guest). Few minutes later four people came for lunch indeed. I drank my coffee rather quickly and left because I sensed a rushing vibe from the owner who seemed not to grant me even the smallest table. (The reviews below I read only later.)
Peak Souk Cafe seemed really nice at the very first sight, but now I guess it not more than OK, as long as you avoid potential peak times and behave submissive or simply don't mind subtle rudeness.
Cons: guests seem not welcome to stay longer, small
