The Whining Pig has amassed a mini-empire of craft beer and wine bars across the Valley. But when its Arcadia location (its second overall) opened in 2017, it was merely a quaint concept squeezed into a narrow strip mall space. Wedged between a hair salon and hydrotherapy business, the tiny spot boasts two chalkboard-painted walls, covered from floor to ceiling with colorful doodles, the voluminous list of hundreds of craft beers and wines available for purchase, or both. Just as eye-catching are the tiny flat screens along one wall, each connected to such old-school consoles as the Nintendo Entertainment System or Sega Genesis. There are also board and card games within easy reach and a vintage Ms. Pac-Man cocktail arcade unit by the door. Feel free to input your initials into the game’s high-score tally or scrawl something in chalk on the walls. But please refrain from carving into the wood-paneled walls of the unisex bathroom as many others have done. That’s piggish.
