First - there are a few high end Asian agencies - eg; Whitebay,
https://www.whitebay.club/. and AEB
https://asianescortyowbabygl.com/ These agencies offer younger, more attractive girls with extensive menus at a higher cost.
The pictures on their web-sites and on LL adv't are much closer to the real thing but are unlikely to be a perfect match.
There are a number of others agencies that rotate their ladies through various locations (Lees, Navaho, Cambridge, etc) They don't have web-sites so its difficult to track who's who and the ladies names are interchangeable. The ladies offered at these locations are most often older and the fee for their services are also lower.. It is highly unlikely that the person opening the door will look anything like the pictures.
If you get lucky, you can encounter some very good providers at these other agencies but it's definitely hit and miss. You're best to be prepared to walk if you're not satisfied with the lady that opens the door. Have the LL ad open on your phone and ask where's "Windy" and if they shrug their shoulders leave.
