I have been to Rol San a couple of times in the past, and have been overcharged 3/4 times. Those experiences definitely left a sour taste in my mouth and I didn't return until last weekend (after a year). Being overcharged by $8 the first time around was okay as we chalked it up as a server's miscalculation. However, being overcharged by a few dollars ($10+) on each of the other two visits (on separate occasions) has gotten me concerned about their practices so I didn't bother to return. Instead of Rol San, we usually alternate between these three; Rosewood, Dim Sum King, or Noble Seafood in Chinatown. I am not the only one who have had this issue, as there are quite a lot of online reviews out there that have indicated this as well.

Despite their lack of service or final bill discrepancies; Rol San has remained a popular dim sum establishment in Chinatown. I can definitely see why as they do offer all day dim sum, and the food was tasty here. As an added note; tea is an additional 60 cents per person.  

The spicy boneless duck feet (3.48).

The shrimp dumplings (har gow) ($3.88).

 The pork dumplings (shiu mai) ($3.48).

The diced beef and preserved vegerables in rice rolls ($3.48).

The shrimps rice rolls ($3.88).

 The chicken feet in chef's sauce ($2.88).

 The spareribs in black bean sauce ($2.68).

The prices are relatively standard to a restaurant offering all day dim sum, and our meal was a little over thirty dollars. I actually did enjoy the food here as I found it rather flavorful, and the shrimp that they used for both the shrimp dumplings and rice rolls were plump and delicious. As for service; the main server didn't do much as all he did was stand at the front counter, and lurked around. Our food was brought out from the kitchen in a rather fast manner by one of the kitchen staff, which is good as it came out hot. Nothing much has changed in a year; good food and mediocre service.
