Welcome to SS Dannyl
The Dome in it's heyday will be remembered as a top notch. Heard lot's of new stuff there!
The three London venues I frequent tend to be:
Solid Hit Soul - Quality underplayed rare soul, very 6t's orientated
The 100 Club - Well what can you say, almost 30 years on still one of the country's top NS nights, only top quality DJ's
Towerfull of Soul - Downstairs River Bar (same as These Old Shoes was) - across the board, something for everybody
Have a look at events page, for other nights.
Hope this helps
