This may be a moderately biased review because I used to be a resident DJ at HY lounge, but if you see past the fact that I get paid to be there and see that I have a different perspective of the entire lounge while the staff are doing their thing, this review might be useful.
The lounge itself isn't the largest place in town , but conveniently located at Yonge and Sheppard surrounded by condos so I know there must be some people out there looking for a local spot to have fun.
Highlight of HY Lounge? The staff. Guys, if you want to be served by some gorgeous girls... try this place out. On top of having a fleet of models to serve you beer, cocktails, shesha, and snacks... the HY Lounge girls are seriously dedicated to making sure you are taken care of and happy during your visit. I sit at the front of the house near the window every Firday and Saturday and watch the place pack up and the girls are all over the place making things work.
They also come up with new shots almost weekly and if you're in the right place at the right time, demo shots for the customers on the house to get a feel for if the new shot will stick around.
Other highlights are live DJs every Friday and Saturday (some holidays too), a Karaoke room in the back that you can use during the week or even book for a party. In fact, you can book the entire lounge if you had a large enough party.
Check this place out!
