Biscuit style is a matter of personal taste, so your mileage may vary, but I loved the biscuits at Gracious Plenty in Prospect. (They have another branch on lower Brownsboro just west of Zorn/Hillcrest, but I haven't tried theirs specifically.) The biscuits at LouVino's brunch were really good too, flaky and fluffy (watch out for that "fluffy" thing, though.
)
We also liked the stuffed and loaded biscuits at Boujie Biscuit and Biscuit Belly, and the biscuits at Burger Girl were okay, although I thought they were a little heavy.
