I found this place at http://www.yourrestaurants.com.au/guide/soul_bistro/ and walking in, didn't expect too much.
WIN (as they say)
Here's their website. Do yourself a favour, Brisbanites, head over there sometime soon. Great service, delicious food (bread, not on the menu, OMG) (and apple crumble sundae, [gf] sounds weird I know but is anything but)!!!! The decor is not amazing and to use the toilet you have to get the key and go over elsewhere, but you win some, you lose some, this is excellent value. And they have a $28 three-course meal.
If you're too lazy to click on the link, it's BYO, it's at 5/16 Baroona Rd Milton.
