On a hill in a residential area in the south of Giv'atayim there is a very pleasant small landscaped park , one of my favorite spots in Giv'atayim. I used to live in the neighborhood in my childhood, and this park holds nice memories.
It is dedicated to the Israeli Air Force, and its pride and symbol is an old Fuga Magister plane overlooking the central lawn (see photo).
If you are not into airplanes you can still enjoy this nice park. Despite its small size it has several romantic spots along its paths set on the hill slope.
Almost everyone coming to Israel knows what falaffel is. But, there are some other fast-food you might want to try. A popular one is an Iraqi dish, called Sabich. It's a deep fried eggplant served with an Iraqi mango sauce called Amba. While this can be found in a lot of places, this place is widely known as the place to get it. This is due to the owner marketing skills.
Givatayim is just a sleeping suburb of Tel-Aviv, not too many restaurants here. Anyway, if you do look for a place to have coffee, a piece of cake and maybe a light meal, Viloa is the place of choice for most locals.
