There is a laundry on Rua Alexandre Herculano, the street where the Post office is & the Kilt & Kelt Bar just off the strip. Its called Preto & Branco about 4/5 doors up from the Geodie Pride restaurant/bar.If you turn left out of Forte Da Oura to the roundabout, turn left and walk up to Ali-Super which is on the corner, turn left again and Preto & Branco is lower down on your right.
Try the Happy house Chinese facing Oura Praia Hotel, all you can eat buffet for 9.95 euros. Mangelos which is just higher up than Forte da Oura going towards the strip @ Wild & Co. Others are Annabelles,
Dos Iramos (2Brothers), Beiros all left at the roundabout on Estrada St Eulalia. There are lots lots more to numerous to mention.

Thanks for your reply I can get the girls to pack less clothes now (I hope !!!!!). by the way how long does it take roughly to walk there in case I have a heavy load...........

Approx 5/7 minutes, its not far.
