My favorite bar "downtown".
Club W is on Delaware, right next to Chippewa. Amazing service and staff, great prices compared to the rest of downtown, and some killer nights during the week (Wed. & Thurs. mostly). Not your typical "hip hop/house music" kind of bar most of the time. My favorite place to go on Friday and Saturday nights (Wed. and Thurs. too if I still lived in Buffalo). I definitely recommend stopping in.
