KSL Mall is one of 5 fairly large malls in downtown Johor Bahru. The others are Danga City Mall, Plaza Pelangi, City Square (right next to CIQ) and Holiday Plaza Mall. The S1 bus will take you between all the malls and runs about every 20 minutes between 10 AM and 8 PM (and less frequently earlier and later in the day).
KSL mall is the newest and has luxury condo towers still under construction. The photo also shows that the area surrounding the mall all has some shops.
Inside the mall there are many choices for clothing, food, and beauty salons. The tenants include Tesco, MBO Cinemas and Sleep to Live. MBO Cinemas is one of the better options for watching movies in Johor Bahru. I would estimate there are over 60 stores (not including restaurants).
Some of the restaurants I like: Sushi King, The Manhattan Fish Market (my one order so far was great and seemed more Malaysian than Manhattan to me) and BreadTalk (bakery). I would guess there are over 40 places to eat.
For the downtown malls I believe City Square is the most used by visitors from Singapore (it is so close to CIQ that it is very convenient). KSL Mall and Danga City Mall (especially for computer and electronic equipment) are the others with the largest amount of Singapore visitors. Though the majority of Singapore visitors go to several of the larger malls outside of downtown, I believe. The malls get very busy on the weekends, with lots of visitors from Singapore, and also others who are off work for the weekend. During the week the traffic in the malls is often very light. The sales staff seems to spend more time using their cell phones (to I am guessing IM with friends) than anything else, during the week.
As with all of the malls I have visited here they have space to let out for daily or multi-day events that usually include incredibly loud speakers. The speakers are often blasting out more than enough decibels to damage your ears anytime you need to get by that area of the mall. I would imagine this helps explain why loud noises don’t seem to bother people so much (once you lose hearing from exposure to lots of excessively loud noise you don’t notice it – because of hearing loss).
