I have been to the Outsider restaurant on George IV bridge before, many years ago with Ed and Mary. Thought I would pay it a visit on a quiet Monday. In fact I ended up eating there on Monday and Tuesday.
The restaurant is on multiple levels, and has some reasonable views of the castle through its back windows. The decor is trendy, and the clientelle (apart from moi) the same. Food prices are reasonable, quite possible to eat there for £10.
First night I ate there, I had a swordfish steak on a Japanese fish broth. I had some mashed potatoes on the side to soak up the broth. I was a little disappointed in this dish. Not sure the broth did much for the steak.
Next day I was much happier with the fish kebabs. Salmon chunks, prawns and scallops on a skewer. Augmented with a salad in pitta bread.
Definitely worth a visit. I am sure it would be very busy on a Friday. It was almost full on a winter Monday evening.
