I'd like to recommend this restaurant though a bit out of our area - Tootoomoo in Crouch End. They describe themselves as Pan Asian and have things like sushi, sashimi, ramen and classic Thai dishes on the menu.
My first time here but definitely not the last - it was all very delicious and fresh. Seems from the menu that they do a fair amount of gluten free, vegetarian and vegan dishes.
Our mains were wolfed down too quickly to photograph but here's a portion of their frozen yoghurt dessert and a lovely cocktail with lychee, guava, rum and ginger.
