BEER BAR Bitter is a beer pub in the Hondoyokocho area of Kagurazaka, known for a lineup centered on Belgian beer, alongside selections from Japan, Germany, and Ireland. The official website says the bar serves three rotating draft beers each week plus seasonal specials, so the focus stays firmly on beer.

The beer featured in the Instagram post is Baeren Brewery’s "Baeren Yamabudo Radler." It uses yamabudo grape juice from Noda Village in Iwate and is presented as a fruit beer with the lightness of a radler, plus the bright acidity and gentle sweetness of mountain grapes. The post keeps the message simple, which makes it read like a straightforward recommendation from the bar.

Food at BEER BAR Bitter includes fries fried in 100% lard and roughly 20 daily dishes. That makes the bar a good match for a berry-tinged radler like Baeren Yamabudo Radler, especially if you want to move between bites and sips without losing the shape of the beer. For drinkers who like Belgian classics but also want a guest beer with seasonal character, this is a strong stop in Iidabashi.
