Wrangler Bar
JD 4 for beer and wine
at Petra Palace Hotel
cosy bar with alcoholic drinks and oldies but goodies music
There is only one restaurant in all Petra at the far end of the Roman Highway, which does a roaring trade despite steep pricing. It also has the valley's monopoly on beer.
For just snacks and hot & cold drinks however, there are a number of small stores and vendors scattered throughout Petra.
Shade is sparse in Petra, and on a hot summer day you can expect to go through at least 4 liters of water and more if you can afford to carry it. The need for water in the winter months is much less. 1.5 liter bottles cost 0.5 JD.
In Wadi Musa, there are many more eating options.
