Thanks Guys for helpful insight and guidance. This is really big information and more useful than what I found from internet by spending a week of search. I might have to spend one more day to cover most of the destination and place of interest.

The only reason I wanted to go to Chinatown is to have authentic Chinese food. And I guess there might be some to try. I will obviously taking day tour to see the city. I am not planning to take rental car because of congested traffic and expensive parking.

Once again, appreciate your help and seek other important info if any.

Thanks
