The app pointed me to The Tastemaker Store after trying to search for Cafes in Tiong Bahru. This cosy café serves mainly some all-day breakfast and gelato, and it is not very spacious. However, the decor was tastefully done, so the place did not turn out too cluttered.
Their French Toast (S$16.80) was probably a little more home-cooked than the usual café style. Thus, even if the taste was not fantastic to rave about, I still felt quite satisfied with it on the whole. And I heard that their waffles are yeasted to achieve that crispy, mildly savoury finish.
