Everyone is right, this IS the best place in Calgary to get egg tarts. They have other things too like cake rolls, sweet buns, savoury buns, etc. which are all very good, but these egg tarts are just FANTASTIC.
Just walk along 3rd Ave and follow your nose downstairs to Diamond Bakery. These sweet, smooth, flaky little tarts will only set you back $1.20! Pretty cheap for a moment in pastry heaven, right?
