What our clients think


We don't know how this day would have been possible without the help of Ragamama Ragasaan. Right from the onset, the event management team really helped us explore ideas not only for the decor, but timings and helped us create our bespoke menu which all of our guests enjoyed! Both parents were told by our guests on how lovely the wedding was. It really does pay to have a team that know what they are doing and deliver above and beyond on the day. THANK YOU
