There is a local organization called Hair for Hope, they do an amazing job. here's their page if you wish to contact them https://www.facebook.com/HairforHopeUAE/?fref=nf
If you'd like to go to a nice beach that plays music during the day I recommend @Nassimi Beach or try @Kite Beach it's pretty cool too. if you want a family style beach then go to @JBR
Well you can go to @SeaView Restaurant in Jumeirah, Order the Seagulls nest there! or @Sea Fu which is a bit pricy but it's absolutely worth it. There's a lounge called @101 Dining Lounge & Bar which has good food if you like lounges or @Fratelli La Bufala - pizzaioli emigrant if you like Italian food.
