Plaza Pelangi is one of 5 fairly large malls in downtown Johor Bahru. The others are Danga City Mall, KSL Mall, City Square Mall (right next to CIQ) and Holiday Plaza Mall. I would put Danga City Mall, KSL Mall and City Square Mall in the top tier and Plaza Pelangi and Holiday Mall in the 2nd tier. KSL Mall and City Square Mall I am pretty sure do much more business than the others do. I like Danga City Mall, but it has some sparse areas on the upper floors.
Plaza Pelangi is a bit smaller and seems less active, than other malls. There is a Cold Storage on the ground level, which is convenient for groceries, but they are expensive compared to alternatives (Tesco and Jusco). Some of the other tenants include: a large MetroJaya, Redbox and Popular Books. The mall has several restaurants including: Sushi King, Coffee Bean, Secret Recipe, Nando’s, Stonegrill and McDonald’s. It has a nice bakery. There are quite a few beauty salons (as there are in all the malls).
Perhaps the biggest advantage of Plaza Pelangi is all the good food nearby. Within a few blocks you have many good restaurants including: Chez Papa, E and Y’s, Rosmarino’s and Warakuya Japanese Restaurant.
Also, when cab driver’s don’t know how to get to those restaurants you can tell them to go to Plaza Pelangi (which so far all have known how to do). The taxi stand at the mall has also always had cabs, which has not been the case at many other taxi stands around JB (for me anyway).
