Fumo Blu is a distinctive nightlife venue located at 270 Rundle Street in Adelaide, South Australia. It presents itself as an underground club/cocktail lounge with a retro‑inspired style—think 1950s aesthetics meets modern night‑life.

Atmosphere & Style
From the moment you step in, you’ll encounter a vibe that blends vintage cool with contemporary bar energy: an intimate, somewhat moody space, soft lighting, polished concrete or brick details, and curated music. Whether you’re there for a stylised cocktail or to dance the night away, the venue balances lounge‑style comfort with club‑style pulse.

What to Expect
A strong focus on cocktails: You’ll find fashioned drinks, creative mixes, and an emphasis on presentation and flavour rather than just standard bar fare.
Club element: Depending on the night, expect DJ sets, dancing, and a late‑night crowd that stays for the full experience rather than a simple drink‑and‑go.
Retro‑underground décor: The aesthetic leans into nostalgia—neon, vintage furniture or bar styling, bold signage—making it as much about the ambiance as it is about the beverage.
A prime city location: Being on Rundle Street means it’s well‑placed for a pre‑dinner or post‑dinner stop, and easy to integrate into a broader evening out in Adelaide’s central precinct.

Ideal For
Groups of friends looking for a stylish night out in Adelaide with cocktails and dancing.
Visitors who enjoy venues with character and design—places that feel like you’re entering a distinct world rather than a generic bar.
Anyone celebrating a special occasion and wanting something a little more elevated (or themed) than the usual pub/cocktail bar.

Considerations
As an underground lounge‑club hybrid, noise and energy levels will likely be higher—if you prefer quiet conversation or intimate settings, it might become lively later in the evening.
Dress code and entry time may matter: Many trendy night‑spots have a “smart‑casual” requirement or start strong after 9–10pm.
Parking/transport: Since it’s in an inner city zone, consider public transport or rideshare for convenience late at night rather than trying to find parking.

Summary
Fumo Blu delivers a memorable night‑out setting—part cocktail lounge, part retro‑club—set in Adelaide’s city heart. If you’re after an evening with style, crafted drinks and an elevated social scene, this venue is well‑positioned to deliver.
