CS, don't think you'll find many great spas period, nvm in St V. Service can be hit or miss.
If you're looking for half service (great bj) with asians I'd suggest Lucy Isabelle in St Boniface, she does wicked bodyslide and cbj. Canna is more central and gives amazing head, full pse. I haven't tried Daisy but she'd be another option, as would The Jess (EI, not asian)
Finally, if you're after half service my favorite reco is Emma. Advertises on Tryst, tiny spinner with lots of energy who will thank you as she swallows you whole.
Hope that helps, enjoy your stay!
