Our take: Fatboy's the Burger Bar consistently delivers on generous portions and classic American-style burgers.
Reviewers frequently highlight the substantial size of their burgers and sides, with many noting they were full after just a burger and fries.
The 'Fat Basterd burger' and 'High Burglary' are often praised for their juicy patties and flavour combinations.
Sides like crispy fries, tater tots, and jalapeño poppers also receive positive mentions.
We think the atmosphere contributes to the overall experience, with some describing it as reminiscent of a US diner.
While the food is generally well-received, some might find the portions overwhelming.
We'd recommend visiting on a weekday afternoon to secure a table easily and avoid potential crowds.
It's a solid choice for an indulgent burger meal, especially if you're in the Upper Thomson area and looking for a hearty option.

Disappointed with the food, seems like standard dropped a lot. Especially the calamari, it was overcooked. As you can see the batter is very dark. Usually, its light golden, I can even accept a darker…
