What is the most unusual or interesting dish you have ever eaten?

I'm not talking about the typical "chicken and broccoli" or "pasta with marinara sauce" dishes. I'm looking for something that was truly unique and memorable.

Here are some additional details that might help you answer:

• Location: Where did you eat it? (Country, city, etc.)
• Type of dish: What was it? (Food category, e.g., appetizer, main course, dessert)
• Ingredients: What were the main ingredients?
• Preparation method: How was it prepared?
• Taste and experience: How did it taste? Was it something you enjoyed or something you found unusual?

I'm open to any type of cuisine, so please share your most unusual and interesting dish, no matter how bizarre or wonderful it may be!
