Usually all smartphones that are not from service providers are unlocked, but in case of already bought phones maybe phone shops on @Al Satwa , would save you the trouble of searching online on how to do it yourself.
@Kcal Healthy Fast Food is one I read about in gulf news, ( www.dinnertime.me ) or www.detox-delight.ae. are also good.
But all three don't seem affordable to many
Lamb chops are syrian restaurants speciality so as long as the restaurant says syrian it's lamb chops are great, there is no best because every chef cooks differently so I cant recommend any specific restaurant.
@Al Safa Park , @Zabeel Park , they're all good parks to play football at.

As in personal experience I haven't seen any specialised in engraving stuff anywhere but usually the shops, would do it for you for an extra bucks or in some cases they'll do it for free. So wherever you buy your jewellery from you can ask them to engrave something on it, they'll do it themselves or send it to another place they work with to engrave it for you and you can receive it a couple of days later.
