Groucho's on Eglinton and Bathurst. I know this is the second place from that location I've proclaimed as being the best at something. (King Falafel down the street has the johnnyhotsauce best falafel honours). I guess this neighborhood knows its food. I do not even live anywhere near this area.
Groucho's has the freshest ingredients, they hook you up with cheese, fresh grated cheddar and a huge honkin' handful of it too boot. Thick paddies, juicy, fresh buns, beautiful vegetables, mounds of grated cheese (Licks style), and an amazing garlic mayonnaise that gives the burger its award winning taste.
Its hard to choose a best burger, we have all eaten bad burgers and good burgers, but let me know where your personal favorites are and what about them makes them great!?
