Shabu Sai offers a wide variety of fresh meats and vegetables, with flavorful broths and good value for money, especially during weekday lunches. The service quality varies across outlets, with some locations providing attentive and friendly staff, while others experience issues with attitude and hygiene. Customers generally enjoy the quality ingredients and the experience of self-service or order via QR code, but concerns about cleanliness, inconsistency in service, and policies like additional charges for certain items have been reported. Overall, it's a popular choice for casual hotpot meals, though improvements in staff training and hygiene standards are recommended.
