Under-hyped - Sylvan, Dennistoun BBQ (best veggie burger I've ever had), Dumpling Monkey (not been there for years but it was one of my fave places to eat as a student. So cheap!)
Over-hyped - Elia (very average Greek food, only one vegetarian main meal option when I was last in), Ramen Dayo (not nearly as tasty as I remember when it first opened).
