    "reasoning": "I need to identify the most important numeric metric in this dataset. Looking at the evidence:\n\n1. From step-1 (inspect_columns), I can see the measures in this dataset:\n   - Average Cost for two (BIGINT, role=measure)\n   - Aggregate rating (DOUBLE, role=measure)\n   - Votes (BIGINT, role=measure)\n\n2. From step-2, I already have the TOP 10 restaurants by Aggregate rating (all rated 4.9).\n\nTo determine the \"most important\" metric, I should consider:\n- Aggregate rating: This is the primary quality indicator for restaurants, ranging 0.0-4.9 with 34 distinct values\n- Votes: Represents engagement/popularity, ranging 0-10934 with 1219 distinct values\n- Average Cost for two: Economic indicator, ranging 0-800000 with 156 distinct values\n\nAggregate rating is likely the most important metric because:\n1. It's the primary quality/performance indicator\n2. The dataset is about restaurant market analysis, where ratings drive decisions\n3. It has reasonable variance (34 distinct values across 0.0-4.9 range)\n4. Other dimensions like 'Rating color' and 'Rating text' are derived from it\n\nI already have the HIGHEST rated restaurants (step-2 shows 10 restaurants with 4.9 rating). Now I need to get the LOWEST rated restaurants to complete the answer."
