If you go to the airport's website, and access the terminal map

click on on "Other" on the little slider thing, and US Airways Club will be #73. If you click on it, it will show up on the map.

We're flying in/out of BUF next month for a conference in Cooperstown and a trip to Niagara Falls, and I was surprised priority pass had the BUF lounge in its program. However, the Anchor Bar is also pretty tempting.
