    "reasoning": "I have comprehensive evidence from 6 successful queries covering ranges, outliers, zero values, currency distributions, and structural integrity. Let me synthesize what the data shows:\n\n1. From step-2: Cost ranges 0-800,000 with median 400; ratings 0.0-4.9 (valid range); votes 0-10,934\n2. From step-3: 18 restaurants with zero cost (out of 9,551); 2,148 with zero ratings; 1,094 with zero votes; 12 distinct currencies; no invalid lat/lon\n3. From step-5: Currency-specific cost ranges show the 800,000 outlier is in Indonesian Rupiah (IDR), which is reasonable given IDR's low denomination (800k IDR ≈ $50 USD)\n4. From step-6: No duplicate Restaurant IDs; ratings stay within 0-4.9 (no impossible values); price ranges 1-4 are valid\n\nI have enough evidence to provide a complete answer about data quality issues. The main issues are:\n- Zero-value records (legitimate but worth noting)\n- Mixed currency units making cross-restaurant cost comparisons impossible without conversion\n- The apparent 800k outlier is actually valid when currency is considered\n- No structural issues (no duplicates, no invalid coordinates, ratings within bounds)"
