"Pantheon" on the Danforth has some of the best Greek food out there. I know the owners quite well.
Shrimp saganaki - Nothing beats this. Shrimp with saganaki (the OPA! cheese) along with some tomatoes and mushrooms. A must buy appetizer if you visit here.
Grilled calamari dinner - some of the best calamari you'll ever try.
Beeftekia dinner - pretty much ground beef burger patties done in a Greek way. Amazing.
Gotta cut it up and squeeze that lemon in there. Dipping into tzatziki is the finisher!
