Here in petah tiqwa we have 5 malls but the greatest one (and the best too) is the big mall near the Beilinson Hospital.
You will find cinema / fast food / stores / restaurants / coffee shops / gym.
The mall called also Ovnat mall and it is the 2nd largest mall in Israel
If you want to walk on a carless street and see cafe's and small stores , more "earthy" you can always go to the hagana Street , its in the center of town.
What to buy: anything you want
What to pay: cheaper than in the malls
