Yes, Paul and other contributors put it very well. I think I said on here before that I christened Camden "Goth Blackpool", because it is a bit like a seafront resort with more tie-dye and Doc Martens than candy floss.
The shops and a large indoor market on the main drag are kinda fun. I don't know if the youngsters care about shopping for clothes, but it's a good spot if they're a bit alternative.
Paul's right that there's markets within markets at Camden. It's a much better market for food than Borough, prices are maybe a bit more reasonable (maybe not these days) and there are actually places to sit to eat outdoors or in "pod" things which are a bit funky. Choices from all over the world, and fusions of many.
If it's a nice day Camden Lock will be buzzing with folks enjoying a drink and socialising outdoors. I know I had a moan about taking kids to the pub in the evening in your other thread, but most will be welcoming of young people in the afternoons. It doesn't hurt to ask if there's any doubt anywhere.
I thought it might be fun to look for some of Camden's music history. I'll post a couple of links I just Googled for -

Britpop of the early 90's didn't really break America, but it was a vibrant scene around Camden and was big news in the British music scene.
I'm not sure how well known Amy Winehouse was in the States, but she's an important figure in Camden music history. A real talent that came to a tragic end too young. I see there's a few guided walks covering her legacy, but here's a link to a self guided walk covering some landmarks -

Grassroots punk rock thrived in Camden in the late 70's. Here's someone's blog entry with some of the highlights

It might be worth looking on Spotify for a Camden Town playlist.
I'd also advise avoiding weekends, especially if the weather's decent. Camden Town tube station is one of the worst. It's totally not fit for purpose and can be so horribly overcrowded it regularly closes for periods on a Saturday afternoons particularly. The 88 bus from central London is a good run up to Camden at a more leisurely pace.
As a last random, Walden Books, possibly one of the best secondhand book shops in London, is in a little residential street just a short walk from Camden Lock. Worth a visit if anyone is into books.
