I ordered the gluten free macaroni & cheese, and a selection of treats.
The brownie was ridiculously good. Rich, moist, and chocolatey, it tasted neither vegan nor gluten free. The cupcake, as well, was very good (only one was for me, y'all). I waited too long to try the cake, so I cannot comment other than to say that two days in the fridge do not do it justice.
I will probably give The Plum one more chance before making a final judgement (after all, I did give Sugar Plum two chances). As of right now, I can recommend it highly for vegan and gluten free pastries, but not so much for the rest of the menu.
I do, however, adore the back patio area
It's quiet, cool, and homey, and was a lovely place to while away an afternoon hour.
