Ryan Chetiyawardana's modernist cocktail room at Sea Containers on the South Bank — a relentlessly forward-looking bar with a menu built around a rotating set of "key ingredients" the team develops in-house. River views, low banquettes, the conversation already half-built into the menu.

The 30-second pitch
Ryan "Mr Lyan" Chetiyawardana opened Lyaness in 2019 in the same Sea Containers spot that previously housed his earlier bar, Dandelyan. Where most cocktail bars have a list of drinks, Lyaness has a list of "key ingredients" — usually six to eight in-house creations that rotate every twelve to eighteen months, with names like "Vegetal Orris," "Onyx," "Fancy Glace," "Coffee Cherry Cordial." Each ingredient anchors a small group of cocktails. The whole menu is the world's most-thought-about set of footnotes.
For a first date this is a remarkable structural advantage. The menu requires reading, comparing, asking questions of the bartender, and building shared opinions about which "key ingredient" sounds most interesting. Twenty minutes of that work disappears before you've ordered a drink. The bar pre-loads the night's most useful kind of conversation.
The moment it makes
The Lyaness moment is the menu negotiation. You and your date are at the bar, you've each been handed the small zine-format menu, and you're trying to make sense of what "Vegetal Orris" actually is. After two minutes of looking, one of you turns to the bartender and asks: "Could you tell us about Onyx?" The bartender — and Lyaness's bartenders are some of the best-trained in London — explains for ninety seconds. They've done this thousands of times and they make it sound like the first.
That ninety-second explanation is the moment. By the end of it, you and your date have learned something together about a thing neither of you knew about three minutes ago. That shared learning — small, low-stakes, mutual — is the most reliably-bonding social experience a first date can manufacture, and Lyaness manufactures it on a schedule.
What to order
Order strategy: ignore the drink names; pick the key ingredient that sounds most interesting to you, then choose whichever cocktail uses it. The Lyaness menu is structured to reward this approach. Tell your date to do the same. You'll end up with two completely different drinks built around two different in-house ingredients, and the cross-tasting becomes the next ten minutes of the night.
The Pacific Ocean Highball. A long-running house drink built around Lyaness's house-made coastal-and-citrus cordial. Refreshing, unusual, photographic. The right opener for someone who hasn't been to a modernist cocktail bar before.
The Cocktail Smashes. Lyaness's house riffs on the punch format — built for two to share. The right round-two move when the night is going long.
"Bartender's choice." Lyaness staff take dealer's-choice requests with relish. Tell them three things you like, three you don't, and they'll make you something only they could have made.
Timing strategy
Lyaness opens at 4pm and the early-evening window from 5pm to 7pm is the magic. The Thames-facing windows catch the late afternoon and evening light spectacularly; the room is at its emptiest; the bartenders have full attention to spare. By 8pm the South Bank crowd has landed and the room is fuller (though never crowded — Lyaness sits about sixty people across its main room and bar).
Reservations are strongly recommended for tables; the bar counter is walk-in. For a first date the bar counter is actually preferable — you watch the team work, the menu negotiation feels collaborative, and the bartenders engage you directly. Sit at the river-side end of the counter for the best of both worlds.
What makes Lyaness Lyaness
Most great cocktail bars rotate their menus seasonally; Lyaness rotates its entire conceptual framework every twelve to eighteen months. The 2024 menu was built around six "characters" with imagined biographies. The 2025 menu is built around six in-house "key ingredients" the team developed over months of R&D. The 2026 menu, just released, is built around regenerative agricultural practices and the producers Lyaness sources from. Each iteration requires the staff to relearn the room and the customers to come back for a new experience.
For a first date this means Lyaness will never feel like the same bar twice — which is a feature for repeat visits, and an aspirational quality for the first one. You're at a bar that takes itself seriously enough to keep changing. Your date will register that even if they can't articulate it.
What it costs
Cocktails are £18-£22, snacks £8-£14. Two drinks each plus shared snacks lands at around £100 for two before service. Lyaness adds 12.5% discretionary service. Total: about £115. Less expensive than the Connaught and the Savoy, fair for the South Bank, fair for the quality.
The bar takes cards, contactless, and Apple Pay without complaint. Bills come quickly. There is no Mayfair-style theatre of the slow bill; Lyaness operates more like a serious restaurant in pace.
Who you'll be sitting next to
Lyaness's regulars skew younger and more design-oriented than the Mayfair hotel bars — late twenties through forties, creative-industries-heavy, with a steady stream of cocktail enthusiasts who follow Mr Lyan's work. The South Bank location pulls a more international crowd than central London on weekends, but weekday evenings are mostly Londoners who've made the trip from the West End or the City for the menu.
Dress code is "you read design magazines." Soft tailoring, expensive trainers, considered jewelry. Showing up in jeans and a t-shirt is fine; showing up in office wear is fine; showing up in formalwear will read as overdressed. Aim for "considered casual."
Failure modes
Your date wanted classics. Lyaness has a small classics list but the bar's whole identity is around the experimental menu. A date who only drinks a Negroni or a Manhattan will find the menu narrow. Fix: pre-flag the bar's experimental nature. If they're truly classic-only, switch to The American Bar at the Savoy across the river.
You went on a Saturday at 9pm. The South Bank crowd lands and the queue starts. Fix: book a table or arrive at 5:30pm.
You skipped the bartender Q&A. The menu is genuinely opaque without bartender explanation, and asking is the whole point. Fix: ask. The Lyaness team are the most-trained bartenders in London at making the menu accessible. Use them.
If Lyaness is full
Seed Library at One Hundred Shoreditch (forty minutes east). Mr Lyan's other London bar — basement-level, more intimate, similarly experimental.
Kwānt in Mayfair (twenty minutes). Erik Lorincz's small cocktail room. More classical, equally precise.
Tayer + Elementary in Old Street. The other modern London cocktail destination.
Editorial verdict
Lyaness earns its #13 ranking by being the most reliable London first-date room for a specific brief: the date where one or both of you cares about contemporary design, sustainability, or modern bartending. For couples in that overlap, the bar is unmatched — the menu becomes a shared interest, the room becomes a small museum of contemporary cocktail thinking, and the night feels like an event without the formality of Mayfair.
For dates outside that overlap, the bar still works but loses some of its magic. The conceptual menu can read as effortful rather than playful if neither of you is invested. Pre-flag the bar's character and Lyaness rewards. Walk in cold and the bar may feel like homework.
