I'd have your customers start to post their reviews on your hotpot page as well as your main pages as well. The posting of the reviews to the hotpot page, for example, is very good with Google although it's not absolutely necessary.
If you were to manipulate the ratings and reviews and add your ratings, etc - I'd use a proxy ip, separate accounts using the IP throughout the ratings and acct creation process as well as building friends across your different accounts.
It gets complicated but would definitely work.
