Came here after getting tired of all the overly fancy, excessive-topping-encrusted burgers usually found around downtown - I was feeling like something basic and old school and Mama'a Boys didn't disappoint. This is easily one of the best burgers in the city that I've had recently. As mentioned, the burgers are no frills - you really only get the usual lettuce tomatoes ketchup etc, but honestly that's all you need. The patty itself was fantastic, thick, juicy with a slightly crunchy crust. Tasted fresh and retro.
The Greek fries that came with the burger were great as well, with a healthy amount of feta cheese and olive oil as toppings. I got a milkshake, which was also quite good - freshly cut strawberries and bananas, and a nice creamy texture.
Highly recommended if you're looking for some excellent, old-fashioned burgers in a no-frills setting and reasonable prices.
