in sthlm there are plenty, but i recommend jolo & co. about 20 tables, well cared for. there's also biljardpalatset with 30 pool tables and 2 billiard tables, and söderbiljarden with about the same setup (maybe a few more billiard tables, don't remember).
at snookerhallen (yes, many places here are called what they are) you have 8-9 snooker tables, russian pyramid and i think 6 pool tables.
all above mentioned pool tables are 9ft and most of them are GC3-GC5. changes may have occured since i last visited the capital but i know they're all still in business.
Biljardpalatset, oldest and biggest in Stockholm, established 1963, 3 floors, 27 pool tables, GC (3,4,5) 9ft, 4 carom tables, 8 Shuffleboards, table tennis, Dart, lots of pool and carom players from 11.00 until closing 01.00 (weekend 03.00).

in copenhagen i have only played in the copenhagen pool and snooker house, pretty expensive but quality equipment. i'm sure there are others. it's a lovely city, especially in summertime. make sure to visit nyhavn:
