@Al Dhiyafa is open 24 hours with an emphasis on Arabic food or @Al Reef Bakery is also open 24 hours you can grab a snack there on your way home. And my favorite is @Arboretum great selection of food and nice views as well!
Personally, I like the manakish served in @Al Reef Bakery as it is freshly prepared and warm and also the one in @bakeria in Dubai silicon oasis headquarters building.
You should check out @Al Reef Bakery . I love their cheese manakish and also the cheese and zatar manakish :) Its freshly made and yummy as well .The only disadvantage I feel is that the seating area is really less, but you could always parcel it as a takeaway.
