There are a few aspects that make Dundas West a unique station on the TTC.
Another unique feature is that, as far as I'm aware, Dundas West is the only TTC station with a McDonalds inside of it. It's even divided in half to serve people that have already paid their fare.
It's also one of the astonishingly few accessible stations on Line Two. I found this windowed walkway that leads to the elevator visually interesting.
Finally, it's the westernmost station where you can catch a streetcar.
The next station is Lansdowne.
