Yumchaa

There is a huge selection of teas here, from traditional lapsang souchong and breakfast teas to Japanese genmaicha and others with names like Russian Caravan - there are samples near the till for you to smell if you're not sure what they'll be like. There's lots of comfy seating and it's a nice, bright and airy cafe.

Wide range of delicious, creatively named teas. Lovely building and location (right by Camden Town station but off ridiculously busy high street). Didn't tend to drink herbal teas regularly (other than mint tea) so has been a great introduction to countless flavours and tastes... i'm converted!
