The most charming market in Qatar, Souq Waqif has recently undergone a major renovation and has been tranformed into an old looking marketplace with smalls shops that sells anything from spices to falcons... It's definatly a 'must see'!
The main activity in Doha, apart from transacting business, is probably shopping in the souks, which here are not the picturesque covered lanes of Tunisia or Egypt, but mostly vast, ultra-modern, airconditioned malls.
There are several country clubs and for those who like it, (personally, I'd run a mile!) golf. The Doha Golf Course costs about US$80 a round on its Championship Course (there is a second course) and looks to be spectacularly in keeping with the city as a whole
and the clubhouse also seems to be on a five star level:
The older, downtown area is reminiscent of less prosperous parts of the Arab world
Fifty years ago expats were sent to Qatar as a punishment. Things have changed tremendously since then, and life is certainly comfortable, but there's not a lot that can be placed in the 'must see' category. There is nothing exotic about the air-conditioned 'souks' in the city centre.
Souks has a street where cafes , restaurants, souvenier shops gather together and become a lively neigborhood at night.
