Tirana is amazing, nearly all the shitty concrete kiosks have gone from the centre and the city is enjoying a kind of renaissance under the mad mayor Edi Rama, who decided the best and cheapest way to brighten up his city was to paint the tower blocks in psychedelic colours.
It's still pretty basic in terms of resources, and the sight of Roma kids begging on busy highways is grim, but it is well worth a visit, for the architecture alone if not for the warmth and pride of the people.
Durres is OK, still plenty of Hoxha's remnants, an estimated 3 concrete machine gun posts for every man woman and child, the paranoid nutter!
Not as interesting as Tirana, to be honest, but it has a nice beach.
Clubs and bars - in Tirana? Well, if you go to the old government quarter where Hoxha used to live, it is now thriving with bars serving good cheap cocktails and the like, it's where the young folk go to drink and show off and you'll be lucky to get a seat in most places.
I would recommend eating out, the Serenata is a top place, and there are many really amazing restaurants that the locals won't hesitate to suggest visiting. Expect to pay about £20 for a three course meal including a bottle of nice wine.
My favourite restaurant was one behind the National Museum (the one with the famous workers mural on it) and I cannot remember the name for the life of me but it was incredible.
Often the social life and the activity depends on the time of year and the day of the week though, when I went, some days many places were shut for apparently no reason... then the next day they'd be packed, it was odd.
Be careful on the roads, they drive like psychopaths and the cars are usually really knackered, avoid little European cars and stick to cabbies who drive Mercs (i.e. most of them).
Some of the high speed antics such as three-way overtaking whilst travelling at 100mph on shitty potholed roads will mess with your head a bit, but if you get a car with rear seat belts (a rarity in Albania) then just hope for the best.
Be aware that many people, especially in the North of the country, are in pretty desperate poverty, so they won't hesitate to nick your stuff if you leave it on show.
Basic common sense and awareness will overcome this.
Have a good time. Tirana rocks.
