Went here with a friend and we were VERY disappointed.
Battle Fields Burger: For the price you pay, I was expecting it to be better crafted. It looked like it was just slapped together. The bun reminded me a lot of a dry McDonald's bun - yellow in colour and no substance to it, y'know? The menu said it was a "crusted" portobello but the crust was more like a thick, tasteless deep-fried breading. I couldn't even taste the mushroom at all! The cheese was excessive and overpowered the taste of everything else. This place isn't good if you want well-crafted food that has any kind of taste profile. This place is better for someone who wants a step-up from McDonald's or Burger King and that could be what you want, but... not for me. I expected more pride... more craft...
Lieutenant Burger: Apart from the fact the 2 patties tasted like 'meat', I felt like I was eating something from a truck stop, with slightly better cheese. The bun could have been replaced with sugar-coated paper towel. Presentation was terrible. The amount of oil dripping from my burger was substantial. The overly loud trap/hip-hop music was horrendous. I was excited to try this place, the sandwich board outside stating to "Join us in our mission of ridding the city of half-hearted and over-cooked burgers and processed cheese." was so hopeful - if Toronto is your battlefield and Burger is your weapon, well... see you in hell, buddy.
