We stopped at Ou Meul Bakkery in Riviersonderend on our road trip. It came highly recommended by Chris and Carla and is definitely well worth a visit. We stopped there again on the way back home, for more pies and pastries, it was so good.
Tannie Rina uses family recipes for the traditional South African inspired pastries. The pies are flakey and delicious, bread is fresh and their breakfasts are a great way to start your day. Coffee is also good and we took some home with us. It is often so packed, with queues out the door and into the street. Luckily we got there early enough to secure our own table and a friendly, efficient waitron. The second time around our waitress (a different one from the first visit) was rather rude and short with us. Hope it was just a once off, bad day for her... That won't stop us from returning though.
If you aren't a regular in Riviersonderend then you can visit their new branches in the Western Cape: Willowbridge, Cape Town and Welgemoed. Riviersonderend is the original, though, and in my opinion has the most character. Visit them all!
