Ioanna Touni launches Fat Rat Croissanterie in Paris

Greek influencer and businesswoman Ioanna Touni has officially launched a new culinary venture in Paris, France. Named Fat Rat Croissanterie, the establishment is located in the Montmartre district and focuses on a variety of croissant flavors, with a particular emphasis on chocolate-filled options. Touni founded the business alongside her cousin, Konstantina Panagou, after identifying a gap in the market for her personal preference of richer, chocolate-heavy pastries.

According to reports dated September 15, 2026, the shop has already begun operations and is welcoming its first customers. Early feedback shared on social media platforms indicates a positive reception to the new croissant bar. Touni stated that the project stems from her long-standing interest in the Parisian pastry scene and her desire to experience high-quality, butter-based creations tailored to her specific taste in chocolate, as she felt traditional pain au chocolat options were insufficient for her requirements.

The venture marks a significant shift in Touni's professional path over the past two years, moving beyond her established influencer career into the international retail food sector. The business is currently active, with owners monitoring initial public response to evaluate the success of their expansion into the competitive French hospitality market.
