Since opening last October, word about Oné Toastbar has been quietly spreading around Luxembourg, let's see what it's all about!
Chong explained to me that after working as a restaurant manager, he wanted to be more hands-on in the kitchen. Not in a big, traditional way, but in a small, personal joint where he could really share his tastes and passions. For him, the sandwich is simply a "support", a canvas that can carry just about anything. After traveling to countries such as China, Japan, and months of recipe testing, Oné Toastbar was born.
When I asked how people reacted to such a particular idea, he admitted he wasn't sure what to expect at first. One of the challenges was how to price it: is it just a sandwich, or is it closer to a dish? Would people come not just for lunch, but even for dinner, or a "sandwich date", as he put it?
So far, the answer seems to be yes. Lunchtimes are steady, evenings a bit more unpredictable: sometimes quiet, sometimes suddenly full. The crowd? More on the expat side, mostly people in their '20s to '40s (which makes sense, who doesn't love a good sandwich?).
The location adds to the charm. It feels urban but not overwhelming. City vibes without too many cars buzzing past, so you can actually enjoy sitting outside.
Inside, the restaurant reflects Chong’s personality: warm, playful, and a mix of everything he’s into. Street art, design, anime, music – all these influences pop up in little details. There's even a retro games console with classics from the '80s and '90s. The seating has options too: cozy corners, a colorful table for groups, all arranged in a way that makes the place feel authentic and welcoming.
The food
I went for the chicken teriyaki, while my friend tried the lobster roll and we split both to taste.
- Chicken Teriyaki (€14,50): mayo, egg omelette, cucumber, carrot, all tucked into a crusty French baguette.
- Lobster Roll (€23,50): toasted brioche with fresh lobster, shrimp, lemon juice, chives, special mayo, and cucumber.
Our favourite? The lobster roll. Who knew brioche and lobster were such a perfect match? The ingredients were fresh, delicious and the sauce was spot on…
Other sandwiches on the menu range from scallops to Sichuan beef, wagyu, and even a Beyond Burger, so there's something for everyone! But the menu doesn't stop at sandwiches: you can also go for katsu (teriyaki, Japanese, Thai style) or a classic Vietnamese bo bun (rice noodle bowl). And for those who are plant-based, the place also has an impressive selection of vegan options, which makes it even more versatile!
To drink, I picked an Ortea Apple iced tea: organic, made in Luxembourg. I love when locals support locals, and it really tasted like homemade iced tea. A super refreshing touch to the sandwiches!
The extras
If you're thinking about bringing kids, I'd say it works best if they're older (12+). It's not the most stroller-friendly spot, and there’s no setup for small children who need changing. The main vibe is definitely young adults to fortysomethings.
And a little teaser: cocktails are coming soon. Think Matcha Old Fashioned, Yuzu Whisky Highball, Lychee Spritz, Porto Tonic… I’ve already got my eye on the Yuzu Highball (future favourite, calling it now).
Final thoughts
What really stood out to me, besides the food, was how genuinely warm and welcoming the staff were. It made the whole experience feel less like eating out at a restaurant and more like being invited into someone's world. Oné Toastbar isn't just about sandwiches – it's really a reflection of Chong himself: his travels, his tastes, his inspirations, all mixed together in a way that feels authentic and heartfelt.
It's the kind of place where you can relax, enjoy something casual but with a creative Asian twist, and just feel good being there. If you're looking for somewhere with personality, warmth, and food that surprises you in the best way, you'll feel right at home here.
