You don't know me at all, so frankly calling me "clueless as fuck" for expressing an opinion on a place I have eaten, with my children, on more than one occasion is a bit rude. Family friendly to me means an atmosphere where I can take my children without them feeling out of place, and where they will enjoy it. Incidentally you can get children's portions for less - £4 for a kids burger.
Oh, and whether or not it can complete with Dosa Sambal is irrelevant - you are comparing a burger with a curry - if I want to take my kids for a curry I'll do that, if I want to go for a burger I can go to Rox burger.
