Many of the bros recommend
www.openrice.com to look for restaurants/cafes to go to eat. It is a great site for food in HK and previously was only in Chinese. Though it did have many reviews in English, one needed to be able to read Chinese to be able to use its search functions. Now the site comes in an English too. Look for the black English button on the upper right hand side.
It will lead to a separate site that is completely in English. It is just like Chinese site and is very comprehensive. You can have a choice of seeing only English reviews or you can see both Chinese and English reviews.
The only noticeable differences I noticed that I hope they will correct in the future are that it doesn't indicate which restaurants have closed down already (Chinese site shows you if place no longer exists) and there is no English version site for restaurant coverage of Macau and Shenzhen which are also covered in the Chinese site.
