In wonderful Chinese fashion and tradition this is a huge banquet room ideal for celebrations in weddings. I see that they have a VIP room upstairs ideal for your bride and groom's grand entrance. It's really a beautiful space that's been thoughtfully curated and designed. We enjoyed the Chilean sea bass clay pot, steamed chicken and mushrooms, shrimp rice rolls and stir fried Chinese broccoli and ginger in garlic sauce. Everything was absolutely delicious. And if you want most authentic more daring items this is a wonderful option as well as they have a huge menu.

My family came here for some dim sum before heading to the airport for a flight back home to NYC. We really enjoyed the dimsum- it was authentic and tasty. There were even items we don’t see back home. Would recommend!

Really big dim sum restaurant with a good selection of food and fast service. We got here at 10am opening on a Saturday and was seated right away. I believe even at 11 when we left, you could probably just walk in and get a table. The radish looking radish pastry was really good and I'm obsessed with the fact that they give you the honey walnut shrimp mayo with your fried shrimp balls. I will say, their highchair quality is ass. The table is too high and the baby just ends up slouching and slipping out. I hope they replace them with better ones at some point.

Diamond Bay is a spacious banquet hall style restaurant with lazy Susan tables perfect for gatherings. The dim sum is great- best chicken feet I have had- not sticky, soft and seasoned perfectly, with a clean aftertaste. Our group of 9 thoroughly enjoyed the ambience and received great service- staff gave us cold water and ordering is super easy with a personal iPad for each table. We liked the Portuguese egg tart, which was crisp hot and satisfying. This place has the food quality and the ease of experience you want in a dim sum restaurant.

Really nice restaurant with excellent quality food. The space is beautiful and the food is amazing with super fast service. Father’s Day was a bit hectic but that’s to be expected.

My new fav dim sum place in Chinatown since Harbor city’s closure. It’s a solid choice with a range of good choices. Not as good or affordable as Harbor city though. :( I’d still give it 4.5 out of 5. The roasted duck and pork were surprisingly good too (much better than some places around Chinatown).

Came in with some friends, great atmosphere, lots of Chinese customers, clearly a cultural gem of a restaurant. Enjoyed tons of food, soup dumplings, duck, crispy fried noodles and chicken, beef and bok choy, everything was great. Getting checked out did take longer than one would like.

Have been here many times for take outs and some quick meals. First time doing dim sum today and it’s meeting my expectations. Good quality dim sum overall with good portion, the chow mien was a little too “broken down” so not what I was expecting. But overall safe choice in Seattle of dim sum.
