Thought I'd pop in for a bit of an update. I am staying in Morningside, and I'd highly recommend it- especially if you get off the main road. I did not, and it's noisy AF. The bus stop is right below my window (convenient!), and the constant noise of vehicles, sirens and late night drunks is making me a bit batty, despite ear plugs.
As for food, the one word I have for eating in Edinburgh is.... disappointment. And the more I've spent, the more disappointed I've been. There have been some unexpected bright lights, but I'm pretty sad about the food in general.
But I'll start with a highlight. This is a place called Maison Bleue Le Bistrot just down the road. (It's one of a group of 3 local restaurants) They have a good lunch prix fixe, so I got the pea soup and the chicken provencale. The pea soup was a delight- I know this sounds silly, but it really tasted of fresh peas. Sometime pea soup is mushy and bland, but this was really great. Little bits of firm fresh peas added texture.
Chicken provencale was quite nice as well, and for 10 quid or so, this was a great deal
Generous portion of thigh meat, needed a little salt. I do wish that people would cut it out with the squiggles, but alas.
Nice meal, charming space, very nice people, would recommend.
