the best repair shop?

All over the place

Brixton Cycles

Not many framebuilders left here. Most assemble bikes on frames from Taiwan. Get a Yorkshire bike - Bob Jackson, Woodrup or Feather ;-)

Repairs? Go to Brixton. But get your wheels built elsewhere IME.

Yes, I ride without a h*lm*t most of the time. Ice is one time I stick a lid on, because it's one of the few occasions it'll do any good. I have two brakes on my fixed. If you ride without brakes, it's illegal but you're unlikely to be stopped (pun intended).
