This is a very cool bar. The leather couches and walls lined with real books like a library was such a nice setting to hang out and sip on specialty cocktails. It's also unmarked, which makes it even more special.
I came to The Lady Silvia during a bachelorette party while we were participating in the Cycle Pub. Unfortunately, we were only able to spend amount 10-15 minutes here. I had their namesake cocktail, The Lady Silvia ($10) with Bombay Sapphire East Gin, St. Germain Elderflower Liqueur, Amaro Nonino, fresh lemon juice, and topped with sparkling wine. It was delicious!
It's a little bit away from the rest of the newer Downtown Las Vegas scene, but I think it's worth the walk or drive. The drinks are decently priced for specialty cocktails, the hang out is really cool, and there's even live music as if people were performing in your living room.
Note: It was announced on Eater that The Lady Silvia closed without notice approximately two weeks ago! Sad face.
