The place is extremely rushy. Cars are not possible to go there because you won't find parking place. What I do is park my car in the Mayo Hospital paid parking (safe and sound), then go out of the hospital's rear gate, sit in a rickshaw or chingchi, and get dropped off at the BABYSHOP.
After buying stuff there, get the toys loaded on some rickshaw or chingchi there, and get dropped back in the Mayo hospital parking!
