Some of the good things I know about them is
- there are many many IITians(met even one of them) who work there - take pride in bringing down the operational costs and do amazing things to produce a healthy meal at less about Rs 5 (may be dated info with inflation)
- one can see their kitchen, in bangalore in ISKON temple - open for public viewing
- last but not the least, some kids whose parents are typically daily wagers, send their kids to such schools only because the kid can have a stomach full meal and bring some home!!!
