Our take: Fatboy's the Burger Bar on Upper Thomson Road offers a comprehensive burger experience, with an extensive menu that caters to various preferences.
We note the consistent praise for their hefty, flavourful burgers, often accompanied by generous portions of fries.
The Burgatory 2.0 is highlighted for its spicy kick and juicy grilled chicken, while the Double Bacon Cheeseburger delivers on rich, salty indulgence.
The Fried Chicken Burger, with its unique dark bun and crispy, seasoned chicken, also stands out as a crowd-pleaser.
We appreciate the mention of their thick, rich milkshakes as a fitting accompaniment.
While large groups might experience a wait for food, the overall atmosphere is described as spacious, friendly, and casual, with thoughtful touches like free plain water.
We think it's a solid choice for a satisfying and hearty burger meal.
Verdict: A reliable destination for substantial, customisable burgers, especially good for groups or a casual, comforting meal.
