I have been tasting many burgers around the world, and I'd remember this one! It doesn't rival the…read morebest of what I tried but it is still a good burger and I'd encourage you to go to try it. By default they cook the beef medium, unless you ask otherwise. And for some reason they expect you to have it medium so they won't ask how you'd like your meet cooked! I prefer medium well, it was ever so slightly over cooked, despite the waitress claims. The meet is good, however it needs plenty more seasoning, so the flavour of the burger won't easily wash away! The restaurant is really relaxed, nice hipster ambiance, kind of more of a café feel, so don't worry too much about dressing up!

Finally had a chance to give Burger Theory a try. Its got a great, close location with indoor and…read moreoutdoor seating, though we did it as delivery. We ordered The Don, The Bo Peep, chili cheese fries, and plain fries. One nice thing about is that their menu rotates regularly and so these items aren't currently on it. First of course, the burgers. Pic 1 is the Spicy Bo Peep, a lamb burger with halloumi and tzatziki. It was delicious but could have been spicier. Pic 2, The Don, was picked for inclusion of chorizo, nduja mayo, and pickled chili and was very well cooked and tasty. With chorizo, nduja mayo, and pickled chilli I expected it to be sweeter but it was still delicious. The chili cheese fries were great, crispy and soft but very tasty. The only complaint was the very stingy application of cheese, we would definitely have preferred more but the meat and chips were delicious. Plain fries were good. Overall very satisfied and would definitely return.

The salad was excellent and made it feel like a much healthier meal. We also shared some chunky chips which were terrific.

Wife isn't a red meat fan so she had the chicken dish and she enjoyed that. Atmosphere inside is beautifully presented. Music in background and nice wooden smoke house type decor.

The Bella burger was superb, flavoursome and unique, especially for a veggie option, but the Big Kahuna, if there was a competition for two dry patties complemented by even drier pulled pork, this would take the cake in that horrendous category. For that burger to win an overall "best burger" award, there would have to be an absolute joke of an awarding body (besides the fact they're already rewarding burger patties) responsible. Not even an ounce of BBQ involved. No sauce. Nada. Dirty fries were incredibly enjoyable, however.
