Perhaps one of Washington Avenue's younger establishments, what Diem lacks in age, it makes up for with a swanky interior and one of the city's best industry nights. "Dysfunctional Wednesdays," Diem's reigning glory, are fast gaining acceptance in the Houston nightlife scene. In quintessential Washington fashion, this small scale lounge features mood lighting, a sleek interior with small sectional plush seating, a well-stocked bar, sultry cocktail waitresses, a gleaming white chandelier and resounding R&B, Top 40's and House music. Word to the wise: come dressed correct or don't bother coming at all.
