The reviews depict Oasis as a nostalgic and traditional Chinese restaurant renowned for its sweet potato porridge and classic dishes. While many appreciate the homely flavors, cozy environment, and reasonable pricing, recent experiences highlight inconsistencies in food quality, elevated prices, and subpar service. The restaurant's move from its original Kallang location to Toa Payoh and now Grantral Mall has impacted perceptions, with some patrons feeling the standard has declined. Despite these mixed sentiments, Oasis remains a popular spot for family gatherings, especially among longstanding customers who cherish its heritage and consistent comfort food.
