Looking for music venues in Lisbon

Hi everyone,

I am currently working an internship in the live music field. I have recently been tasked to research music venues in the city of Warsaw, with a capacity of 250 or less. These could be bars, speakeasies, clubs, etc. Looking to book shows with solo/acoustic artists. Does anyone have any venue suggestions? I am based in America, so I figured I'd ask on reddit first to help start my research.
