Input: Really good Dim Sum, I recommend you try this restaurant. It's impeccably clean, airy, and has very good service. We tried the pork shui mai, pot stickers, shrimp dumplings, hot and sour soup. Ingredients were fresh, the food was not greasy and flavors were excellent. Best dim sum I've had in Las Vegas.
Output:
4 stars
