Nicholas is one of the last vestiges of what I think of as Camden - and I wouldn't change it for the world! He makes a lot of money burning those that allow themselves to be and is a cantankerous ummm, I'm new here, insert your preferred expletive...HOWEVER - you can do "a deal" with him IF you have the patience and have done your research thoroughly. It's like shopping in Thailand - offer 1/3 of what he says and work from there.
He never burnt me and has furnished me with several outfits in the last 10 years or so. Aperture is a much nicer place to go when you want something - you won't be patronised, everything is fairly priced and the coffee is good too - but if you want a thingummy for a blah blah and you need it by tomorrow, Nicholas will come through.
