Brasserie Um Tennis - Diekirch

Okay selection of craft beer, but customer service is not up to speed. A group of rowdies came in and loudly played their own music, with the owner having disregard for other customers.

Nice terrase on a sunny day. Food was ok. Went for the burger which could have been great if the patty wasn't a piece of burnt-out coal.

Horrible experience at this restaurant. We booked for 3 during lunch hours. We arrived around 12:00, sat inside and the older lady took our order. We were waiting patiently for our food but after an hour and a half still no sign that our food’s about to be served. We then decided to just leave since it’s absurd to wait that long. Also, no one even came to our table to at least explain why it’s taking so long. As we were about to leave the older lady said that the food is coming (in a very cold way). Since she said it’s almost done we just waited a bit more and then the food arrived. My acquaintance who ordered pizza found out after having a few bites that the parmesan had mold in it. He showed it to the other staff and I guess she apologized for it. He refused to eat the rest since he saw there’s more mold. It was difficult to finish our food after having seen the mold on his pizza. We still wanted to pay but they told us that we didn’t have to. The other lady staff apologized to us but not the one who sat us and took our order which I consider UNPROFESSIONAL AND RUDE. Never coming back here again.

Great, cosy restaurant with lovely food ans friendly staff. We visited here after a long day hiking. The burger (Elsacian-style) with potatoes and garlic sauce on top was simply delicious. The accompanying fries were terrific as well. We've had a lovely dinner here and would definitely come back!

This is just perfect! It has avery cosy atmosphere, the people seem jolly and friendly, the staff is attentive and fast. Most importantly, the food is excellent. I love Wäinzoossis , and they dod it really well. The sauce did 'nt seem to be overloaded with cream, it was just fabulously well balanced, the dame blanche was scrumptious. Also, they have a nice selecrion of drinks. Recommended!
