SF hound needs help Ft Worth

Dear wife is heading to Ft Worth for week long conference in mid March. I'd like to find her some good places to dine with colleagues. I'd say a varied menu with some meat,fish and some good Tex Mex might be ideal choices. These same choices can be at one venue or a mix. This will be for dinner. The group could be as large as 10 or as small as four.

Any great Mexcian places would be especially appreciated.
