I'm going to Edinburgh for a conference on Weds and am arriving around 11:15 at Waverly Station. I have 2 hours to grab lunch somewhere between the station and the uni (Teviot Place) by myself and would like to spend no more than £15 at some place tasty but casual. I eat anything but especially like Middle Eastern/Vietnamese/Thai. Scottish is fine too (I live in London). £15 isn't much, but if you have suggestions please fire away! Are there food trucks in Edinburgh like in London? Cheers!
