On June 14, Marumugi offered five draft beers, ranging from a crisp pilsner to hop-forward and dark styles. Sizes were listed as large 1,200 yen plus tax/extra and small 900 yen plus tax/extra, making it a practical list for both a quick stop and a more deliberate tasting session.

The first beer on the list was "Pilsner" from Mojiko Retro Beer, described as having a sharp bitterness and a refreshing finish. Next came "Itsunotou / NO.10 IPA" from Shiga Kogen Beer, an Imperial IPA at 7.5% ABV. The note highlights bright hop aroma, assertive bitterness, and a light body influenced by sake rice.

Also on tap were "Hoppy Weizen" from Minoh Beer, presented as a fragrant, fruit-forward wheat beer; "Mayo ttaracono Pale!" from Ushitora Brewery, an easy pick when you want a pale ale; and "Third Wave Porter" from VECTOR BEER, a porter that is dark yet described as surprisingly fresh.

Marumugi is a small beer pub on the second floor of Ichibankan Building in Arakicho, Shinjuku. Its position near Yotsuya-sanchome makes it an easy stop after work, and the clearly differentiated lineup gives beer drinkers a straightforward way to choose according to mood.
