Strolling through Cherry Creek North's Fillmore Plaza, populated with modern glass towers and upscale boutiques, it is easy to walk right past this fashionably obscure nightspot. The bar resides in the basement of the four-story Janus building. But this place is anything but sterile. Roo Bar consists of two basic rooms: a pool room with six tables covered in purple felt, and a dark smoky lounge by the bar, housing comfortable sofas and large booths to sit back and enjoy a good conversation. The food menu offers standard bar food such as burgers and wings, but the famous martinis are superb.
