    "reasoning": "I've already profiled numeric ranges and found some concerning patterns: 18 restaurants with zero cost, 2148 with zero ratings, and a maximum cost of 800,000 (likely in a different currency than others). I also see 12 distinct currencies which could cause mixed-unit issues. Now I need to examine the currency distribution and check for inconsistencies in categorical fields like Rating color/text alignment, and look at the Cuisines field for formatting issues.",

    "sql": "SELECT Currency, COUNT(*) as restaurant_count, MIN(\"Average Cost for two\") as min_cost, MAX(\"Average Cost for two\") as max_cost, MEDIAN(\"Average Cost for two\") as median_cost FROM raw.\"Zomato Restaurant Dataset\" GROUP BY Currency ORDER BY max_cost DESC",
    "purpose": "Check currency distribution and identify if the 800k max cost outlier is due to currency mixing"
