Happy House

Located at 68 Rue Emile Mark in Oberkorn Differdange, Happy House is an Asian restaurant and one of the most popular in southern Luxembourg. This family-run establishment offers traditional Chinese cuisine as well as a selection of Japanese sushi, all at prices considered reasonable for the area. Customers have several options for dining in, taking away, or having their meal delivered.

The establishment is open from Tuesday to Sunday, offering both lunch and dinner service. Specifically, it welcomes customers from 12:00 PM to 2:30 PM and from 6:00 PM to 10:30 PM Tuesday through Friday, and only in the evening from 6:00 PM to 10:30 PM on Saturday. On Sunday, it is open from 12:00 PM to 2:30 PM and from 6:00 PM to 10:30 PM. Monday is the restaurant’s weekly closing day. The restaurant can be reached by phone at 26 58 15 86 and also has an official website where customers can view the menu and place orders online.

A varied Asian cuisine à la carte

One of Happy House’s main strengths lies in the diversity of its culinary offerings. Unlike many Asian establishments that rely solely on a buffet, this Chinese restaurant has opted for a carefully curated menu where each dish is prepared to order. Customers can thus enjoy specialties such as Peking duck, flambéed garlic prawns, Thai red curry chicken, stir-fried noodles with Chinese mushrooms, and dumplings. The sushi selection is particularly highlighted and receives regular praise: many patrons consider it simply the best sushi in Luxembourg, especially for its freshness and elegant presentation.

The menu also includes convenient takeaway options for lunch, such as popular noodles and cheese yakitori. The house specialty remains the fried ice cream scoop, recommended by many visitors. To complement your meal, the restaurant also serves wine and beer, allowing you to fully enjoy dining in.

A friendly and well-maintained setting

The ambiance at Happy House is frequently praised in customer reviews. The setting stands out for its simple yet effective decor, clean and stylish enough to ensure a pleasant experience. Although the room is modestly sized, the atmosphere is warm, friendly, and calm. Many regulars particularly appreciate the attention to cleanliness and the kindness of the staff, who are regularly described as smiling, welcoming, and attentive to their customers.

The service is generally responsive and professional. The servers take the time to explain the dishes, can accommodate specific requests—such as preparing a vegetarian croquette that wasn’t initially on the menu—and ensure the meal runs smoothly. This attentiveness greatly contributes to the loyalty of a local clientele who have been returning regularly for many years, sometimes for over a decade.

Some drawbacks to consider

However positive they may be, some experiences shared by customers deserve to be highlighted to allow everyone to get a complete picture before going to the restaurant or placing an order.

• The wait can be long, both in the dining room and for delivery, especially during peak hours or on weekends.
• Some customers consider the portions small, especially in relation to price increases in recent years.
• Some deliveries arrived cold or significantly late, without always being accompanied by a proportionate commercial gesture.
• The price of certain drinks (water, wine) is considered high by some customers.
• Charging for delivery bags is perceived as a lack of transparency by some users.
• The removal of the old all-you-can-eat buffet disappointed regulars who appreciated this format.
• A few isolated incidents (hair found in a dish, burnt or undercooked dishes, rubbery noodles) have been reported.
• Telephone communication regarding takeaway orders is sometimes considered to be in need of improvement.

Eat in, take away or delivery

Happy House offers three distinct dining options to suit all preferences. Dine-in remains the preferred option for fully enjoying the atmosphere, the freshness of the food, and the quality of service. However, the dining room has limited capacity, which may explain some longer waits on busy evenings.

For those in a hurry or wishing to enjoy their meal at home or at the office, takeaway service is available directly at the counter. The website also allows you to pre-order and pick up your order, a significant time-saver. Finally, home delivery is offered within a defined radius, with drivers generally described as friendly and courteous. However, it should be noted that deliveries outside this area may incur an additional charge, and the stated delivery times are not always met to the minute – something to consider when ordering in advance.

A word about perceived quality

A review of all customer feedback clearly shows that Happy House enjoys strong customer loyalty, maintained by consistently high-quality dishes over many years. Many loyal customers of ten years or more continue to actively recommend it. The Chinese cuisine is considered authentic and refined, while the sushi is presented as a true house specialty. Value for money remains one of the most frequently cited advantages, especially in a country where the cost of dining out is high.

However, the gradual price increase, combined with a perceived reduction in portion sizes, has led some former customers to diversify their shopping habits or switch to competitors. A few incidents related to delivery or the occasional inconsistent quality of certain dishes have also deterred some customers, although these cases remain a minority compared to the overall volume of positive feedback.

Verdict for future customers

Happy House remains a reliable choice for anyone wishing to discover or rediscover Asian cuisine in Differdange. Sushi lovers will find a renowned local favorite, while those who prefer traditional Chinese dishes will appreciate the varied menu and the freshness of the ingredients. It’s advisable to book in advance or arrive early in the day to avoid queues, especially on weekends. For takeaway or delivery orders, it’s best to allow more time than indicated, particularly during peak hours.

For any practical questions, the restaurant can be reached at 26 58 15 86, and its website allows you to view the full menu and set menus. Whether for a family dinner, a quick lunch with colleagues, or an evening with friends, Happy House offers an appealing balance of authentic Asian cuisine, generous portions, and affordable prices in the southern Luxembourg culinary scene.
