I'm cautiously a fan of the new Milton Markets (actually a relocation from another market). I don't know about the old location, but the new one is convenient by all three of Brisbane's major modes of public transit, and also eminently driveable. It tends to be a packed house, full of bad pedestrian behavior but good vendors.
The range of sellers here is eclectic and upper crust, even compared to its numerous competitors. They have some very expensive (but very good) bakers, an entire stall devoted to nut milks, a french toast truck, and, at least the last time I went, adoptable greyhounds. They also, for a market of this size, do very well on actual vegetables, including an organic farmer and several other substantial stalls. Indeed, they've got things for all sorts of people; if you want to make ultra-healthy food at home, you can come here for ingredients, and if you want to indulge, you can stop by their fudge stall. People with restrictive diets should be pretty happy; a South American stall offers to cook their breakfast dishes with cactus instead of egg (and their beans are tasty), and a variety of decent options abound. This market is mostly food (though there are a few tents of clothing and other sundries).
I would suggest avoiding this place if you are a compulsive spender, as there are a lot of ways for your money to disappear fast. But since I'm self-disciplined (and my exchange rate is favorable), I find it worthwhile to visit. read more
