We've tried many dim sum restaurants in this area, and Ocean Star on recommendation. We were seated promptly, but in 40 minutes at the restaurant were able to order only 3-4 dishes. This is because we were not seated on an aisle, and every cart seemed to turn the wrong direction. I felt like standing on my chair and yelling for service. I didn't. We were so hungry that we finally hailed over a taro cake cart and seemingly feasted. We soon regretted that because it was so greasy. 20 minutes later we were lucky and got our favorite-- shrimp noodle, which was OK. We had only ONE dumpling cart pass in those 40 minutes despite about a dozen passing along the aisles, and the supposed vegetable dumpings had a very gamey-tasting sausage; we returned that one and ordered a vegetable dumping from a waiter. That waiter then avoided our table (like the carts did), and we abandoned all hope. Submitting to the dumpling gods' disfavor, our fourth dish was a cold sesame bun with red bean paste, which was filled with a pocket of oil. 6 hours later, the taro cake is still turning in my stomach.
Pros: Only small wait on the weekend
Cons: service depends on whether you sit on the aisle/corner; not enough dumping carts; food too oily
