Good restaurants for lobster in Downtown Dallas and/or Downtown Fort Worth: any suggestions?

I would like to spend my birthday at a nice restaurant in either downtown dallas or downtown fort worth. I really want lobster and while red lobster is the obvious choice, I don't want to go to a franchised restaurant for my birthday. I want to go somewhere different with a fun and casual setting, such as razzoo's, joe's crabshack, etc. I found a pretty decent restaurant called, daddy jack's, located in sundance square in downtown fort worth [an area which i love], but the menus not quite as good as red lobster's. right now daddy jack's the #1 contender but i'm open to new suggestions. keep in mind i don't want to go to a franchised restaurant chain!
