If you have never been, Chinatown is adjacent to downtown Honolulu. A cultural time capsule that appears to me as not a "tourist destination". Although I think it is a spot well worth exploring. I have been there 4 times, and each visit unveils new idiosyncrasies that draw me back.
Make no mistake, this is not a "Pirates of the Caribbean " ride. These are real people participating in commerce that is their livelihood. Do not hang around after dark. Expect homeless littered about. But the point being, this is a real marketplace of a different culture, and the intrepid traveler will enjoy discovering an environment that offers exotic foods, languages and commercial interaction that one will not experience if one stays in the hotels in Waikiki.
This is not a clean mall. It is an area of a few square blocks where other cultures along the Pacific Rim are well represented It is somewhat dirty, and again, there are homeless about. Please be careful and aware of surroundings as you walk around. The vendors are for the most part polite and not aggressive. Myriad choices of authentic foods and crafts.
Enjoy your visit-
