Mong Kok’s trendy dining scene just got a whole lot more personal—literally. Popular Western-Japanese fusion restaurant 90s Lazy has revived its wildly anticipated “Identity Card Offer,” giving Hong Kong diners a chance to slash their entire bill based on the digits and letters hidden in their HKID numbers.
The promotion runs from September 28 to November 1, 2026, at the restaurant’s retro-inspired branch at 1–2/F, 50 Shan Tung Street, Mong Kok. The premise is simple: check your Hong Kong identity card against the letters in “90SLAZY.” Match one character and enjoy a 10% discount; match two for 15% off; and hit three or more to unlock a table-wide 30% discount—the equivalent of a hearty seven-folds for the whole party.
Here’s the best part: only one person at the table needs a lucky ID number. Whatever the highest match among your group is, that discount applies to everyone’s meal. It’s a clever incentive for friends and colleagues to band together—and a compelling reason to check whose card carries the winning combination. To claim the deal, diners must follow the restaurant’s official Instagram (@90slazyhk) and present their physical Hong Kong identity card to staff before settling the bill.
A Feast for the Eyes and the Palate
Beyond the promotion, 90s Lazy has carved out a loyal following for its 1970s Japanese Showa-era aesthetic. The space is defined by deep walnut-brown furniture, sweeping stained-glass windows, and ornate painted glass lanterns suspended from the ceiling—vintage, warm, and refreshingly spacious. It’s the kind of ambiance that feels both nostalgic and Instagram-ready.
The menu, meanwhile, traverses East-meets-West territory with confidence. Diners can expect a rotating lineup of pastas, risottos, pizzas, shareable snacks, waffles, and desserts, all executed with a playful Japanese-Western twist. The fusions fit the venue’s personality: comfort food with flair, served in surroundings that feel decidedly more boutique than casual chain.
Numbers, Details, and How to Join
No complicated app downloads or advance reservations are required. Just gather your crew, bring your physical HKID, and confirm your matches before paying. The restaurant operates daily from 12:00 PM to 10:00 PM, with tables available for both walk-ins and larger gatherings.
Promotion highlights at a glance:
- 1 matched character: 10% off the entire table
- 2 matched characters: 15% off the entire table
- 3 or more matched characters: 30% off the entire table
For those keen to maximize the deal, the strategy is simple: bring along your luckiest friend. Since the best single ID determines the group discount, a table of six can all benefit from one person’s exceptional luck. A quick check before you go could make for a very satisfying meal.
A Growing Trend in Hong Kong Dining
90s Lazy joins a broader wave of Hong Kong restaurants turning periodic promos into playful rituals. From identity-based deals to flash sales on fast food and groceries—this season alone, chains like Fairwood and Circle K have rolled out time-sensitive offers—it’s clear that savvy operators are leaning into exclusivity and gamification. These stunts don’t just drive traffic; they create conversation pieces and shared dining moments.
With over five weeks left to take advantage, the identity card offer is more than just a discount—it’s an invitation to rediscover a local favourite. Whether you’re planning a catch-up with old friends or a team dinner, it might be time to check that ID number twice. You never know: three letters could be all it takes to unlock something worth toasting to.
