Underbelly is a family-owned basement bar beneath Seattle's underground in Pioneer Square, accessible by descending two flights of stairs. This polished dive blends chic decor with the grit of historic Seattle, serving French vibes through craft cocktails, natural wines, cold beer, hot pizza, and specialty bites like Tartes Flambèe and grilled cheese. The space hosts burlesque shows, local musicians and DJs, poetry readings, and pop-ups by local chefs. A true hub for Seattle's arts and music community. Open daily from 11:30 AM.
