Shamrock has been an institution for decades. Their burgers were juicy and delish then and they're still today. Flame grilled, standard toppings, plain kaiser, well seasoned, onion rings and fries. Very small location. Maybe 6-8 seats. Friendly staff. Easy to read easy to select in confusing menu. Not too many options. In my opinion one of the best burgers in Toronto.
Last time I went they took out the PAC-Man game that was there for ever. Boo.
