First of all Lost in Marrakech is not a restaurant but a laundry service
I visited lost in Marrakech after spending a 4 days in the High Atlas I had no clothes when I returned and the hotel that I was staying at charged 20 MAD per piece to get them washed. I met someone who recommended Lost in Marrakech - and sure enough they charge a very cheap 20 MAD to wash and dry your dirty pants.
The only downside is I found it difficult to find and there isnt really any Signage.
