Another institution of West Nicolson Street is Susie's Diner, a relaxed veggie cafe where I have been known to teach my students. Their noticeboard is one of Edinburgh's useful places to find ads for rooms to let. Eat their tortilla, but, as in most wholesome places, be careful about pudding.
Avalanche Records is good for indie records and new stuff that's a bit off the beaten track: Edinburgh bands, Glasgow bands, American lo-fi... I go there for The Pastels, Jad Fair, Ganger, that kind of thing.
Finally, I cannot leave the street without mentioning the Pear Tree. Once upon a time, the Pear Tree was a really nice pub with really nice beer and really comfy furniture and really nice staff. In particular, it usually had Younger's No. 3, of which I am rather fond. It used to be the place you went when your rendezvous screwed up, because you'd probably meet someone you knew, or at least someone worth killing time with until whoever you had planned to meet figured out that you'd gone to the Pear Tree.
However, this pub is no more. Rumour has it that the owners asked the police to bust the place. The staff lost their jobs, the furniture was replaced, they hired much less cool people and made them wear uniform polo shirts, and they took away all the good beer. Grown men wept.
If anyone knows of a pub selling No. 3, please tell me.
