Old Dirty is a gastropub and live-music bar tucked inside the Aqua Project complex on Phahonyothin Road, a short walk from BTS Saphan Khwai. The room leans rustic with modern edges, and the crowd is mostly local, in their late twenties and thirties, there for the draft list and the weekend bands as much as the food. It runs daily from 5pm to 2am, which makes it one of the later options on this stretch.
The draws are three: a deep roster of imported draft beer, a gastropub kitchen that moves between Thai dishes and Western plates like steak and salads, and regular live music. Weekend shows kick off around 8pm, and Thai artists occasionally fill in the weeknight slots. With 1,833 Google reviews averaging 4.8 stars, Old Dirty has built a steady following as a live-music bar in Saphan Khwai, Bangkok.
You can sit inside among the exposed beams and mismatched furniture, or take a table outside if the weather behaves. Service is quick and casual. Arrive before 8pm on a Friday or Saturday if you want a seat with sight lines to the stage, because the room fills once the band starts. Order a draft, work through a few plates from the gastropub menu, and stay for the set. Conversation is possible between songs and at the outdoor tables when the music is playing.
The pull at Old Dirty starts with the tap list, which leans heavily on imported drafts rotated alongside cocktails and wine. From the kitchen, the steak is a regular pick among return visitors, grilled to order and paired with the kind of sides you want after a couple of pints. Salads get ordered more than you would expect for a bar this loud, and the Thai side of the menu runs in parallel for the table that wants som tam with its lager. Live music is the other signature, with weekend sets from 8pm and Thai acts dropping in midweek.
Old Dirty sits at 490/21 Phahonyothin Road inside the Aqua Project, a small cluster of bars and restaurants in Saphan Khwai. BTS Saphan Khwai is the closest station, roughly a five-minute walk south along Phahonyothin.
