do children at sri swami chinna jeeyar international school in kukatpally carry lunch?

a friend whose daughter goes there talked about it at a birthday party last week and i haven't stopped thinking about it. she said it felt calm, which is more or less the one thing i'm looking for. we'd mostly been looking at ib schools, so this is a bit of a turn for us. from himayatnagar it would be a long day for our son, and he's the slowest eater i know. most days his tiffin comes back two-thirds full. so the practical question: does the school serve lunch for the primary classes, or is it all from home? and how long do they get to eat?
