I'm pretty sure this should be listed as a 3 hour tour. There is a ton of food so come very very hungry. I'm sure the guide is a very nice person but he seems easily frazzled and I'm not sure how much he truly knows about Chinatown. Several people left for various reasons so I'm not sure if there is a time management problem on the part of the guide or there should just be three hours allotted for this tour and people are expecting two. I would also recommend starting this tour elsewhere in Chinatown. Grant Street is just too crowded at the time the night tour starts and perhaps the tour should start an hour earlier so people are more able to wait to eat during the tour and we won't be inconveniencing business owners and vendors that want to go home. I'm sure some little tweaks like this will make this a good tour but there are a lot of them that need to be made, hence the two star rating.
