No - character dining at Liberty Tree was discontinued in January 2009 (with a brief resurgence in Jan/Feb 2010 while Crystal Palace was closed for refurbishment)
There are two possibilities generally discussed as to why, and they were not mutually exclusive of each other:
1) Cost cutting
2) MK had 5 TS restaurants, and three of those were character meals at dinner.
As for what the actual reason was, Disney didn't share it.
