Brasserie Guillaume

I’ve been going to Brasserie Guillaume for years and the quality of food has always been exceptional and consistent. Fresh produce, perfectly cooked. You can tell a lot about a quality even from bread they serve. Honestly, in 15 years I’ve been going there (3-4 times a year), I’ve always had a great meal and have recommended it to colleagues from abroad & clients knowing that you can simply not go wrong eating there. Always happy to return there!

From now - my favourite place in Luxemburg ♥️ Seafood is the best - huge and super-tasty!!! We took Gillardeu oysters 🦪 N.1 and Sea almonds, both were HUGE and fresh!!! The fish soup and scallops with mashed potatoes with spinach were again - HUGE and enormously tasty! Already saved this place for the next visit, just the very best recommendations ♥️

We passed this restaurant during a tour, we saw the fresh seafood and decided to come go dinner after a long day of sightseeing. We arrived a little after 5:30pm, main dining area tables are busy or have reservations until 7pm. We were accommodated in an area near the bar with 2 small table. They put the 2 small tables together. And we were very comfortable. Service is good, seafood is very fresh. Very good taste. We were so pleasantly surprised dogs are allowed inside the restaurant, we loved it. My tuna steak was perfect. Rice had a seafood flavor also. Everything was delicious. Totally recommend.

Always excellent food! The fish is great and they serve the absolute best tartelette aux framboises. But the food is expensive and the restaurant can get quite busy.

In 2020, when I first visited this restaurant in Luxembourg, my experience was far from pleasant. Despite having made a reservation, I was greeted with a curt remark about speaking French, and when I arrived, there were no tables available. I was eventually seated after a 30‐minute wait, which put me in a bad mood right from the start. To make matters worse, it took another 50 minutes before someone finally took my order. I left vowing never to return. However, in February 2025 I had a lunch meeting, and this was the only available spot, so I decided to give it another chance. Almost immediately upon arrival, I felt unwelcome as a foreigner. One staff member at the bar directed me to go upstairs, only to be intercepted by the manager, who greeted me in a dismissive tone. When I mentioned that I had been told to go upstairs by a colleague, the manager claimed that his colleague was mistaken, and I ended up waiting at the bar. I overheard unkind remarks about me from the staff, and while I waited for at least a drink, a local guest was promptly attended to and received a drink well before I did. When I finally asked for a menu and inquired about ordering a champagne, I was once again told that the person at the bar didn’t speak English. Despite the restaurant’s attractive ambiance, I never felt welcome, and considering that my lunch came to a total of 250 euros, the overall experience was extremely disappointing.

Amazing food. The crab was excellent—fresh, full of meat, and served with tasty mayonnaise. Five stars. The ray wing was also excellent. Five stars. Good portion sizes and very reasonable prices. Excellent service. If you are in Luxembourg, don’t miss Brasserie Guillaume.

My wife and me went to this place for celebrating our anniversary. We reserved a table upfront (recommended at the weekend) and got one on the first floor. Personally I would prefer the first over the ground floor as it offers more privacy; the ground floor is nice as well but more for a casual occurrences. Usually I am not a wine expert but the waiter provided based on the food a excellent recommendation. To eat we got the cold plate with a mix of everything - if you want to try a lot of different types of seafood the plate is your choice 😉 we have eaten nearly 2.5h in a very relaxed manner and couldn't finish it as it's more than it looks like. Service is superb. Skilled staff, very friendly and helpful and especially proactive. Even once the restaurant was completely full, speed of service was excellent. Really recommendable place to have a nice dinner :)

The seafood quality is no doubt, fresh and high quality. Still, it’s in Luxembourg, so the food price is doubtlessly high.
