I've been to Alexandros numerous times and this is by far THE best place to get gyros in the GTA. I've been to Greece a few times and I definitely can say these gyros are the next closest thing.
Nothing is over done. Just the right amount of everything. I have had a few pork pieces that were too crunchy for my liking, but it does not take away from how delicious Alexandros is. I usually get a mix pork/chicken gyro. You need to ask them to add fries to the gyro though (at no extra cost). I mean that's how they do it in Greece right? Their greek fries are also perfect. So simple, yet so yummy.
This place seems like it's open 24 hours! Any time of the night you decide to come, these guys/gals are open. PERFECT after clubbing meal.
