Tsunami

The Verdict

Tsunami has been earning its place at 20 Glyde St for over 20 years, the World of Fine Wine 2-Star Accreditation confirms this is not a restaurant coasting on longevity. For a special occasion dinner in the western suburbs of Perth, it is one of the few venues in the area where the food, the drinks list, the atmosphere are all working in the same direction. Book it for a date, an anniversary, or any meal where the setting needs to do some work. If you are looking for a casual weeknight feed, you can find cheaper and easier options elsewhere in Mosman Park.

The Experience

Tsunami runs two distinct formats under one roof: Tsunami Izakaya, a Japanese fusion dining room, Tsunami Ko, a teppanyaki bar where the cooking happens in front of you. The teppanyaki format is the stronger choice for groups and celebrations — the theatre of the grill gives the meal a natural energy that a static dining room cannot replicate, it tends to suit larger tables without the awkwardness of a shared menu. The Izakaya side suits couples or smaller groups who want a quieter, more composed experience.

The drinks program is a genuine differentiator here. The venue has accumulated a wine, sake, whisky list sourced specifically to complement Japanese cuisine, the World of Fine Wine accreditation is a direct signal that the list has been vetted by people who know what they are looking at. For most Perth restaurants at this tier, the drinks list is an afterthought. At Tsunami, it is part of the proposition. If you are coming for the sake pairing or want to explore Japanese whisky alongside your meal, this is one of the few places in Perth's western suburbs where that conversation is worth having with the staff.

The garden setting — sheltered by vines, lit by fairy lights, is the room to request for a date or anniversary dinner. It reads as deliberately romantic without tipping into theme-park territory. Inside, the walls stocked with bottles create a warm, cellar-like atmosphere. Both rooms work for a special occasion; the garden is the better call in the warmer months, roughly October through April, when Perth evenings are warm enough to sit outside comfortably.

Service at a 20-year-old independent venue in a suburban Perth location can go either way: deeply experienced or complacent. The fact that Tsunami is still earning external accreditation after two decades suggests the kitchen and floor have not settled. The drinks accreditation in particular requires ongoing curation, which is a staffing and management commitment, not just a historical achievement. That said, specific service claims beyond what the data supports are not something Pearl will make here, what you can reasonably expect is a team that knows the menu and the drinks list well enough to guide you through both.

Timing and Booking

Booking at Tsunami is direct. It is not a 6-week wait, it does not require a credit card hold or a waitlist. For a weekend dinner, especially Friday and Saturday evenings, book at least a week ahead to secure the garden or a teppanyaki table. Midweek bookings are easier to arrange on shorter notice. The teppanyaki bar seats are worth requesting specifically when you book; they tend to fill before the main dining room on busy nights.

Optimal timing: aim for an October-to-April evening booking if you want the garden. For the teppanyaki experience, a weekend sitting gives the format more energy, a half-empty teppanyaki bar on a Tuesday is a different experience than a full one on a Saturday.
