Walked by the restaurant and thought the place looked nice and trendy. When we stepped inside, the decor was inviting and pretty. We were greeted by a very grumpy male server who didn't even say hello. He just saw the two of us and grabbed the menus and walked to a table. We (2 of us) looked at each other and figured he was indeed taking us to our table. We ordered some items (e.g. shrimp toast, hai-gaw, beef balls, etc) I did notice special items are about $8 per dish. It's high for dim sum but I was okay with it as the restaurant's location and atmosphere gave an upscale vibe.
Another server took our order sheet and he was marginally better. At least he acknowledged our presence but don't expect smile and pleasantry.
Food: good but not the best. If I feel like dim sum, I would go to this place for dim sum.
Service: Non-existent! Grumpy servers. Sometimes a cheaper low-end dim sum place in chinatown has way better service than Kwan Dim Sum. I wonder if the owner cares?
For the price, food quality is justifiable but there is definitely discrepancy with the service offered at this place.
Side incident: during our lunch, a lady came in to order takeout at the counter. She had a small dog with her. The dog was running around on its own in the restaurant. We and other diners all saw this. Finally one gentleman asked loudly from his seat to her, "is this your dog?" She smiled and came and grabbed the dog. The server who was taking her take-out order didn't seem to care that there was a dog running loose in the restaurant. I am not sure about the law and regulations, but thought it was odd that a dog was allowed in the restaurant like that. When she came back to pick up food later, the server who gave her the food even played with the dog a bit.
Conclusion: food is fine, service disappointing and terrible.
