Tasty Box HK Bistro - Authentic Cantonese Dim Sum & Barbeque in Diamond Bar, CA

Wonderful place to pick up your dim sum favorites! Got the century egg porridge and the wrapped glutinous rice and both tasted excellent. It was really nice to be able to enjoy some dim sum without the noise of the dim sum restaurant. Will definitely be back here for more in the future

Great value! Took 5 minutes to order and get the food at noon on Saturday. $10.99 for duck plate and +$2 for chrysanthemum tea.

Exceptional Hong Kong style Dim Sum place. Small but yet it doesn't matter as their Dim Sum are fresh and delicious. I'd say much better than many traditional dim sum restaurants in LA.

Diamond Bar eatery with takeout dim sum. They’re currently open during covid for takeout and do have some tables outside for outdoor seating, though most people just used the tables to wait for their food before leaving. There’s ample parking as it’s in the H Mart plaza. Credit cards are accepted but there’s a 5% discount if you use cash. The cashier is super friendly and you first pencil in your order on a slip of paper, and then you’ll provide it to them and pay. It took about 10 minutes for our food to come out on a Sunday around noon, which was pretty quick seeing as there were at least five other parties. Food-wise, they have all the tasty dim sum favorites. The BBQ pork baked buns particularly stood out to me for how light and airy the dough was. Similarly, the pineapple buns had a great texture with just the right amount of sweetness in the filling. The quail egg shu mai was cooked inside (which I hadn’t seen before) and I was glad to have tried it, although I still prefer the regular siu mai. The fried pork bun (xian sui guk?) was also very yummy. They have pictures of the food inside on their overhead menu if you have difficulty choosing. Overall, it’s a good option for dim sum if you don’t feel like driving out too far and are in the area.

Ok, if your mission is great dim sum for a fair price, this is the place. People drive miles to munch on traditional dim sum favorites. Bao and shumai are tasty. I like the milk tea too. Get a mix of things and share. The red bean paste sesame seed balls are excellent (ごま団子).

Came here on a Thursday for some dinner to-go. There were around 2-3 customers when I dropped by around 7pm. I got a garlic veggie and a crispy noodle. Both were super delicious. The veggie sauce made it just right seasoning. Would definitely come back for some dim sum next time

I recently visited Tasty Box, and true to its name, every dish we tried was absolutely delicious. The Dumplings with shrimp were perfectly crafted, with a delicate wrapper and a flavorful filling that left us wanting more. The Spareribs in black bean sauce were tender and rich, with a savory depth that made them an instant favorite. The West Lake Beef Soup was another standout, with its hearty and comforting flavors, making it the perfect dish to round out the meal. Each dish was well-prepared, and the quality of the ingredients really shone through. The portions were generous, the presentation was appealing, and the flavors were spot on. Tasty Box truly lives up to its name, and I’ll definitely be back to explore more of their menu. Highly recommend!

No frills DIMSUM DELI in the southern section of Diamond Bar. Food is tasty and inexpensive. You can choose to dine in or eat at the benches outside.
