I've been coming here for 2-3 years now, and mostly during the peak morning hours. It is an ideal location to stop by for your coffee regardless if you are hopping back onto the highway (401 West ramp) or exiting off Port Union East. Very convenient which also makes it very busy during peak times.
The staff here are probably the best Starbucks employees I've ever encountered compared to any other location in the GTA. I once got a drink which was made wrong, and they re-made it free of charge! How can you go wrong with considerate, mindful and very friendly customer service. That's not to say they usually make my drink wrong, because they've only done that to me once.
I love it here but there are other customers that come here that ruin the experience for me by treating the employees unfairly for Starbucks policies that they have no control over. It's disgusting to witness when other customers feel entitled to treating the employees so rudely.
