Summer Açaí is popular for its generous portions, fresh ingredients, and friendly service. Customers appreciate the variety of flavors, customizable options, and engaging environment with board games. However, inconsistencies in portion sizes and service quality, especially at certain outlets, have been noted. Some find the bowls too sweet or watery, and issues with order accuracy and staff attitude have been reported. Despite these concerns, the overall impression is positive, with many considering it one of the best Açaí spots in Singapore, valued for its taste, value, and welcoming ambiance.
