Maple hasn't really changed in years ... just the location, everything else is the same.
The MPA turnover is still high IMO and yes they are all Asian last time I was there. You can expect the same level of service as you have received in the past ... as long as they don't think that you are LE or they recognize you.
Last time I was there I saw a chinese lady, mid 20s, B cups slight frame named Mimi/Mi Lei/Meh Meh? ... didn't speak that much english but knew how to take care of my needs.
