I've been a regular at the Auld Hoose for several years, since before I went vegan. The food has always been good, and they were the first place I frequented that offered vegan cheese (I'm lactose intolerant so have been dairy free for over a decade before going vegan). Once I went vegan, the great vegan options they offer, all clearly labelled on their menu, were really welcome, and made me feel welcome in my favourite pub, even though I was now eating ethically. The menu has a lot of vegan options, not just a few sad choices, so there is plenty to enjoy.
The pub has just recently reopened after a refurbishment and redecoration, and it looks great. It retains the casual, comfortable feel, but with a smart new look. The pub is a favourite among University of Edinburgh students, offering a student discount and is the meeting place of several student societies. It is also a welcoming haunt for members of the goth, industrial and rock scenes in Edinburgh. And yet, it is plenty welcoming for anyone passing who wants to enjoy good drinks and good food (in gigantic portions - particularly the nachos (vegan version available)).
Cons: Can get very crowded
