Lennon's sits on the 30th floor of Rosewood Bangkok, which tells you two things before the needle drops. It is a polished hotel cocktail bar, not a basement audiophile den. It is also unusually committed to records for a room in this category, with more than 6,000 vinyl titles and a setup where guests can browse and play selections with staff help. The music brief is broad but recognisably record-led: jazz, blues, soul, funk, Motown, classic rock, and the kind of late-night catalogue material that suits a skyline bar better than a lecture-hall listening session. The emphasis is on the library and the ritual rather than model-number display. The records are part of the room's identity, not a few sleeves placed behind the bar for effect. Go for the intersection of hotel bar ritual and vinyl ceremony. The cigar lounge, private rooms, and 30th-floor setting make it more dressed-up than most listening bars, but the large record library gives it a credible reason to be here. Best for someone who wants a serious drink, a view, and a chance to choose the next side without pretending they have wandered into a Tokyo jazz kissa.
