Kuay teow neua is a Thai beef noodle dish, where "kuay teow" translates to "noodles" and "neua" means "beef." It's a popular street food in Thailand, especially in Bangkok.

The dish typically consists of rice noodles (often the flat, wide kind, similar to what's used in pad thai) served in a beef broth, accompanied by slices of beef (it could be a mix of tender beef slices and beef balls). The broth is simmered for hours, usually with bones, spices, and herbs, to achieve a rich and flavorful taste.

It's often seasoned with various spices and condiments, such as star anise, cinnamon, and soy sauce. You'll commonly find it garnished with bean sprouts, cilantro, green onions, and fried garlic. On the side or at the table, there might be condiments like sugar, chili flakes, fish sauce, and lime wedges for diners to adjust the flavor to their liking.
