For Denmark (Copenhagen- all in the centre of town):
Photografica http://photografica.dk/ is pretty much the place to go for film shooters in Copenhagen. Prices are a little high but that's Denmark for you...(they do have occasional bargains in their sale in Jan- also in the 'junk' bins full of old bits of camera)
-Huge range of used gear (shiny window full of 'Blads, Leicas and Rolleis covered in my drool)
-Film of all kinds. Discount for buying 10 rolls or more (lots of instant & sheet film- expired film in bulk too)
-chemicals and darkroom gear
-24hr developing service done by
Laboratoriet (pretty much the only pro lab left in town- very good- will push, pull, cross-process anything you ask really). Cheaper to go here than Laboratoriet directly for small quantities of film (<10 rolls or so. check before as prices change)
Foto/C http://www.foto-c.dk/. Not such a huge range of stuff but a little cheaper.
-Some used film gear (mostly 35mm)
-Lots of film & chemicals (last time I checked they still had a few rolls of Kodachrome...)
-Developing service (E6 & 120 also done by Laboratoriet)
There are also plenty of other small places but these tend just to sell a limited variety of 135 with not much choice & a limited range of gear. Of these
Njal Photo is
http://www.njalfoto.dk/index.htm is probably the biggest and best. Most of these places will develop C41 in 135mm but for 120 see above
