During my visit to India, I saw many shops in India use Tally, DacEasy,Wings etc.Tally is the most popuplar.Its good to use original s/ws rather than copies ones.

For resturants there are other biling softwares designed esp :for hotel/coffe shops, it requires another type of inventory mgmt & KOTs.Many s/ws are available in India,but many shops order custom s/ws.

If you are new, might as well try this Microsoft® Office Accounting Express or Microsoft Office Small Business Accounting. I heard it does the jobs quite efficiently.
