Been coming here almost daily for the past week since been too lazy to pack a lunch and snacks during the work week and Pumpernickel's lighter lunch options are starting to grow on me! Pretty affordable if you have a small and plant-based appetite. My favorites have been the yogurt parfait (vanilla non-Greek yogurt, sugar-y granola, topped with wonderfully fresh berries) for $2.50, small soup for around $4 (they have daily vegetarian options, but be warned that since the staff fills your container the soup will consist mostly of liquid rather than solid ingredients), and the small salad (2 choices - quinoa, tabbouleh salad, couscous, lentils, etc) for around $5. Animal proteins are more expensive, e.g. salmon + sides is around $15. Whole fruits here are $1 per apple or banana.
Tip- consider walking 1 block east to Sobeys or Metro for their pre-made lunch options (e.g. $8 salmon with sides at Sobeys vs. $15 at Pumpernickel's) and cheaper fruit by the pound.
