Driving from Masua to Buggerru you'll find a sign indicating Cala Domestica. Well just 450 metres before that, on the right side (inland) there is a dirt road winding through the valley. Follow the road for 2.2 km, until a widening where the river has destroyed the road. From here follow the path going up and walk inside the gorge.
As the gorge gets narrower, after 5 minutes of walking, you'll find on your right-hand side the sector Istentales. After a few more minutes, just over a ford, you'll find the sector Piazza Pulita.
Keep on walking 1.5 kilometres, passing all the other sectors. Banana Republic is the farthest sector inside the gorge, and it is just by the road. As you approach it you can see its back side: a flat overhanging slab. That's the "Side A" sector, while "Side B" is the one by the road
