The same is happening post covid to Gateway Ekkamai. Mostly of coffee shops are now closed, as well as Educational, Yoga, Toys, stalls.
In my view as often happens here in LOS, landlords are trying cover the previous year's losses by doubling rents and tenants just give up. May be the value of the area will eventually justify a luxurious condo vs a relatively old mall and both malls will disappear in some years from now.
