You'll need to do a little driving.

Because almost all the gentlemen's clubs in Dallas are clustered in one area of town -- off/near the stretch of I-35E south of 635 (aka LBJ Freeway).

The Lodge and the Men's Club are the best for upscale topless, and Baby Doll's nearby is also topless and a fun place, though more of a laid-back place. Bonus: They're basically all on the same street, so if you get tired of one, try another.
