Hello
@kcfaye!
You'll need to make your days jam packed so that you see as much as possible in the short amount of time
Glasgow is a bit of a foodie heaven for me, I always have the best meals there! Some personal favourites are Stereo, The Flying Duck, The 78, Mono and Steak, Cattle and Roll. Take your pick - they are all great!
While in Edinburgh if you're wanting to do the Mary King's Close tour then you'll have the castle, the Royal Mile and the Grassmarket all in the same area which will be handy, as well as a few Harry Potter fan sites - Greyfriars Kirkyard and The Elephant House cafe (if that's your thing!). There's plenty more to see in Edinburgh but those attractions will take a full day quite easily!
Foodwise on that side of town I always enjoy Ting Thai Caravan (one of
@Horizons favourites too!) as well as Paradise Palms or the good ole Baked Potato Shop on Cockburn street for cheap and cheerful.
Hope this helps!
