I can't give a totally accurate review because I haven't visited bunners - but my friend who lives in the junction brought me several items to try. Keep that in mind while reading please :)
So my friend picked me up a loaf of bread, a chocolate cupcake and a cookie sandwich.
The bread was great! Super tasty and I really enjoyed eating it. Downside? After a few days it got REALLY hard and so about half went in the trash. Next time I'd freeze it sliced up (which I do believe they suggest)
The chocolate cupcake was meh. The icing was great but the cake itself was dry and crumbly. Made a huge mess trying to eat that thing!
The cookie sandwich was two chocolate chip cookies with a cream filling in between. The cookies were pretty good - nice flavor to them, but the cream was dry and tasted kind of funky.
So a few things to note - these items were all gluten free and vegan. I can make really great gluten free baked goods that are soft and not crumbly but once you take away the eggs and dairy it probably gets a lot more complicated. Despite not really enjoying the bulk of what I tried, that wouldn't actually deter me from trying more (or going to the actual location). They have a huge amount of choices (though from what I understand, what they have varies on a daily basis) and I think they've probably got some real gems in there.
