An izakaya is Japan's answer to the after-work pub: small plates, cold drinks, loud rooms. FEN Modern Izakaya brings that formula to District 1 — not a quiet omakase counter, but a neon-lit dining hall where karaage, squid tentacles and chicken cartilage fly out of the fryer onto wooden tables.
The room is the signature. Hanging FEN kanban boxes glow over graffiti walls and niches of figurines; a pixel-tile maneki-neko watches over red paper lanterns. It reads Tokyo on the walls and Hanoi in the noise — two street-food cities that understand each other.
FEN sits at 240 Lý Tự Trọng, open every night from 18:00 to 02:00. Late tables fill fast — call ahead.
