Sea Straw

I believe you may be referring to a dish called "sea urchin" or "uni," which is a type of seafood commonly found in restaurants, especially in sushi restaurants, in the United States.

Sea urchin is a marine invertebrate that lives in oceans around the world. Its gonads, or reproductive organs, are considered a delicacy in many cultures and are often used as a sushi topping. Sea urchin is known for its unique flavor and texture, which can be described as buttery, sweet, and rich, with a soft and creamy consistency.

When ordering sea urchin at a restaurant, it is usually served as sushi or sashimi, with the urchin roe placed atop a bed of rice or served on its own. Sea urchin can also be used as an ingredient in pasta dishes, soups, and other seafood preparations.

If you have never tried sea urchin before, it is recommended to start with a small amount to see if you enjoy the flavor and texture. Some people find sea urchin an acquired taste, while others enjoy it right away. Additionally, it is important to make sure that the sea urchin being served is fresh, as it can spoil quickly and may not be safe to eat if it is not properly handled.
