I have heard Tallinn described as being the "Babe capital of the world" (even more so than Prague), so please Michael, use your camera to prove or disprove that claim :-)
Whatever the motives of the Russians in building the Orthodox cathedral it is a lot better looking that most Soviet buildings.
Nor do the major buildings of a city all have to be in the same style - indeed having buildings of different styles can be nice. For example, I have no problem with a mixture of classical and gothic buildings in a city (although they can jar sometimes if right next to each other - in depends on what sort of "classical" and "gothic" style we are dealing with).
As a general rule of thumb the question to ask is not "are all the major buildings in the same style", but "do all the buildings look like they were designed before 1914"
I know this is a bit hard on some modern styles of building (which can be good) - but it is a general rule of thumb.
It is even true of housing.
The Victorian working class houses may have been terrible places to live (big families in small, cold, damp houses) and the cottages of pre Victorian times may have been terrible to (for the same reasons).
But improved and with less people in them they are fine - they look O.K.
The council houses of the 1920's and 1930's mostly look ugly (even if they have a lot of money spent on them) and they stand out in their uglyness in so many towns and villages in the United Kingdom (and even in the Isle of Man).
As for post World War II government housing - best not to think about it.
Of course major office buildings are known for such things as one having to have the lights on during the day, the rain leaking in and all sorts of other problems.
At least the old "cult of concrete" seems to be going, but it does seem to have been replaced by a "cult of glass" (the glass buildings look better, but I have a feeling there are going to be problems).
The beer is excellent, and inexpensive. (A half litre of beer costs 30 kroon (about £1.30) in bars in central Tallinn - probably less in less fashionable areas). I have been drinking a style of dark beer that appears to go under the name of "tume". I have had quite similar beers in Poland, although not under that name.

This would adequately describe any former Soviet city with a population over 200,000. The Soviets might have been utterly useless at most things, but they were excellent at churning out stunning women.
