Found this shop by random a few years ago when I was exploring Botanic Gardens. The tiny shop serves coffees, yogurt and limited baked goods (but no microwave to reheat them) and imo the best item would be this sticky bun! Smothered in cinnamon sticky sauce, the bun itself was soft and fluffy. If you're petty about your bun, do take away so you can reheat it up for your tea-time snack but normally I'll just have it there as my fuss-free cheap dessert thrill.
P/S: I used to frequent Simply Bread for sticky bun but the quality there has been dropping and they did close down for quite some time. This is definitely close or even better than the last Simply Bread's sticky bun I had.
