Sankt Gallen TAP ROOM is a beer pub directly operated by Sankt Gallen, located near the north exit of Hon-Atsugi Station. Promising beer delivered fresh straight from the brewery, it serves up to 20 different beers on draft across 20 taps. The "taste all 20 varieties" set, consisting of about 150 ml x 20 glasses, costs 6,600 yen and lets guests sample everything from core beers to limited releases in one sitting.

The lineup spans traditional styles such as Golden Ale, Amber Ale, Pale Ale, the TAP ROOM-exclusive Weizen, and Brown Porter, as well as YOKOHAMA XPA, Brut IPA, Imperial Chocolate Stout, Orange Chocolate Stout, and Sweet Vanilla Stout. In addition, flavor-driven beers like Sankt Gallen Sakura, Whey Sour Ale Strawberry, Apple Cinnamon Ale, Shonan Gold (Orange), Winter Fruit Tart Ale, and Ink-Tasting Beer are also on offer.

At the stronger end of the spectrum, the selection also includes Barley Wine El Diablo 2025/2024 and Wheat Wine Un Angel 2025/2024, making for a very wide tasting range. The shop also serves pizza baked in a stone oven and cheese dishes, so from a light, crisp pour to a rich, aged beer, guests can enjoy pairing each drink with food in sequence, which is part of this place's appeal.
