I had bookmarked Union Station since I start writing Yelp reviews.
It is hard to rate Union Station since it is in a constant stage of renovation. It has so much potential but it really needs a lot of work. But at least it is going towards the right direction.
Being a transportation hub: Go Train, TTC, VIA, UPS, it is used by locals and tourists on everyday bases. A lot of the logistic, set up and facilities are just so dated and need a modern update. I do love the historical look of the facade and the main hall area.
Hopefully after all the renovation and upgrade, Union Station would earn a 4 or even 5 star for me.
