Beachcombers good with kids especially younger ones they have a play area with playstations etc colouring and the like for tiny ones.

If your going to be in town of a Friday, book in advance the Friday Bruch at J W Marriot. The have a great bruch and an awesome kids section set up. They won't want to leave, honest. It's a huge room, just for them. Taxi's are cheap and it's an all you can eat and drink. Really great food too! Friday Brunch in Dubai is a must do.

Noodle house is good , very reasonable, Shimmers is an outside venue on the beach and i think more of a lunch venue nice salads/club sandwiches etc, possibly to hot for the kids as the beach will be damm hot when you go, and to humid to enjoy it in the pm. I found in July shimmers to warm to really enjoy what i was eating.

JBH which is only a buggy ride up from the private beach/promerade and they have some pretty decent places and im sure they have a pizza/italian on the beach but that is inside as well.

Toscanno a small italian/pizza/pasta resturant at madinat and very reasonable id also recommend trader vics.

The brunch I think would be great but I personally feel its more adult/formal esp with the copious amounts of booze that is consumed, that is one of the reasons they are so popular as most have free champers , young kids could get bored and not really enjoy the experience of having to sit in there sunday best for a few hours when they could be in the pool.

So if i was going for a brunch id def go with one geared to families, but to be honest if you stick with just the hotel resturants, your bill will add up, id def get a cab down to the marina where there are many resturants and a good place to people watch.

There is also a hard rock cafe near to the GHH and there used to be a planet hollywood at the wafi centre i think.
