I think the Italian you are talking about was the old pizza place which is now closed and chicken shop in it's place? There is a nice Thai restaurant called Chern Thai on Grove Vale that should be open at lunchtime Saturday. I am veggie too btw. Peachy Goat in Herne Hill is good, but depends on the ask as it's kinda burgers and pasta and not the cheapest. I tried the Turkish in Herne Hill, Saray, round the corner Saturday before last and will be quiet but the owner is super sweet and it's not expensive. If you are happy with pizza / pasta, you could also do Dai Due Fratelli which is good food, friendly and attentive service at good prices on Lordship Lane.
