Tasty bread on Mill? Proof is a bakery specializing in sourdough breads and the three items we got here were carby gluten filled goodness! Margherita Pizza - pillowy bready crust topped with basil and tomatoes. Tasty portable snack. Sourdough croissant - flaky croissant goodness with a slight sour taste. Delicious French bread - haven't tried it yet but judging from previous visits to proof should be good! The best part is because of the sourdough base you don't feel bloated or terrible after. Def worth a visit and the location on Mill is icing on the cake for students. (If you visit them during holiday or special times during the year they have some seasonal items that are delicious like a Ukrainian Paska) read more
