Grandma's Secret is a Vietnamese-inspired basement speakeasy hidden beneath a blue light that hums softly above a short flight of stairs. Upstairs is where Nana feeds the neighborhood at Lela's Bistro, but downstairs is where she unwinds in this intimate cocktail lounge. The space can hold only a dozen or so guests, making for an exceptionally cozy and exclusive experience. Open Wednesday through Saturday, this walk-in-only bar features creative drinks with Vietnamese twists on old favorites alongside house-made Vietnamese-inspired snacks. The small menu reflects what's offered upstairs but in more intimate, limited portions. Grandma's Secret proves that true speakeasies thrive on exclusivity and carefully guarded secrets.
