The Shipwreck Lounge is wonderful bar and one of my favorites. The owners have done a tremendous job with this place. The red sangria, cosmos, and Mojitos are perfect for a hot summer day (not so much a fan of the white sangria). The bartenders are friendly (especially Gary), and the layout is fantastic; blending a great indoor room with a perfect outdoor area with an AMAZING glass fire pit.
My only complaint is I was really saddened when they got rid of the baby grand piano. Sniffle... Even so... I still love the Shipwreck. There are other bars in Provincetown that are also great, but they're also usually playing loud music. Shipwreck is more laid back and a little more classy. I'm bringing one of my best friends there next weekend.
