No. Not is like that crazy cbd shop. I guess anyone is a regulars at SS nd 108 Mirage can book..first in first served .
Not that complicated. Once the wechat is up just text them make a booking ...that simple!!
I reckon most the time , u have to book ahead..it's like Ginza etc
108 more than 85% is booked out.( not a good idea to walk in) Mari is booked out every week she is on even before the roster is out.
