This looks just like a normal pub, but the menu clearly indicates a number of vegan options, including burritos (huge), tacos (even more huge - though they do suggest that you share them between 2) and falafel burgers (didn't see any while we were there, but I'm guessing they were probably enormous too!). There are also vegan breakfasts on the menu, although they don't start until 12pm.
The staff were friendly and helpful, and our food arrived quickly. My ginormous burrito took up half of the plate, the rest was occupied by rice and salad. It was a little spicier than I was expecting, but the heat was nicely balanced by the generous helping of guacamole.
The pub was fairly quiet when we arrived (6pm on a Monday night) but was getting busier when we came to leave later.
If you're hungry, vegan, and in Edinburgh I'd recommend a visit!
