With its low-slung ceiling, windowless walls and stained-glass mermaid paraphernalia, Atlantis Lounge approximates a ship’s hold. Though it may not be as committed to its nautical theme as, say, Linnton’s Lighthouse Inn, remember that this bar looks out on a pizza parlor, not the mighty Columbia, and the music outside is likely to be a painfully earnest bluegrass set. A cushy black booth spans two walls, hugging beat-up wooden tables and facing a narrow bar where a bartender prepares cocktails designed less for salty-mouthed sailors than for a Caribbean cruise—think guava coladas and lots of scurvy-thwarting orange juice.
