Zwanzig23 by Lukas Jakobi

I thoroughly enjoyed the dining experience l. Wasn’t sure what to expect, but every dish was created with a unique favour and combination. As someone who hates plain foods and enjoys strong or intresting flavours it was a 10/10 for me. The concept of no waste also great and I love it! The atmosphere is pretty chill which is nice as often places with diamond experiences or high quality foods are very proper and feel like it’s hard to relax. The owner and workers were all friendly. My favourite were the scallop dish, deserts and the zero waste starter. The only thing I would change is slightly decrease the amount of food because we were incredibly full after haha! But great job and in my opinion it’s worth the money:)

For a restaurant holding a one-star Michelin distinction, the standard of service should be notably higher. While the food was well executed, the drinks enjoyable, and the concept and atmosphere may appeal to some guests, the overall experience was significantly diminished by consistent service and coordination issues. We visited as a group of five to celebrate a birthday and were seated at the communal table rather than the bar. Regardless of the seating concept, a genuinely guest-focused approach should be expected at this level. When we politely asked whether the music volume could be lowered to allow for conversation, we were told it would remain as the owner preferred, a response that felt dismissive and set an unfortunate tone for the evening. Several operational shortcomings followed. Our menu order, which included a mix of vegan and non-vegan options, was delivered incorrectly, and the final bill did not reflect what we had ordered. Despite bringing this to the staff’s attention, the matter was neither acknowledged nor corrected. Requests for still versus sparkling water were repeatedly confused, further adding to the sense of disorganization. Dietary requirements were handled with insufficient care. Despite clearly communicating the need for a fully gluten-free menu with gluten-free bread, the bread was forgotten twice and we never received clear confirmation that all dishes were suitable. Vegan dishes were also mixed up at the table. Additionally, although English menus are available, we were repeatedly given German menus and had to ask more than once for the correct version. Considering the price point and the restaurant’s reputation, the experience was disappointing. While some guests may appreciate the concept and ambience, it was not the right fit for us. The idea of chefs presenting their own dishes is a thoughtful touch, but significantly stronger coordination and more professionally trained service staff are needed to deliver an experience worthy of its status.

I had a wonderful meal here last night. The concept is a tasting menu. You choose either "vegan" or "not vegan" when you book. As a vegetarian it was great to be catered for and very clearly on the website. Just a small shame there was no dairy really, which probably made it less filling than equivalent dishes would normally be. The real standouts are the flavours though. As I was told when presented with the amuse-bouche, when Lukas does sweet, it's properly sweet, when he does bitter, it's properly bitter etc etc. For me, the white asparagus sorbet (palate cleanser) with Thai flavours was absolutely epic. I could mention 3 or 4 other dishes I loved too. Service was attentive and friendly. Every dish was explained by the chef who had made it (you sit on stools around the open kitchen and watch them make everything). Lukas himself gave the background on a couple of them. He and all the others spoke excellent English. Drinks service was great, very knowledgeable about the products. I had a Belgian chardonnay and a fruity red that's served cold - paired perfectly with the pea dish, which was a perfect taste of spring! It's not cheap but for a 1 star meal that actually offers superb service, great tasting and very clever food with nice range of textures and influences, I'd highly recommend. No doubt the michelin inspectors will be re-issuing the star again next year, perhaps even pushing 2. It sounds from social media like Lukas has plans to build a bit of an empire and on this evidence I wouldn't be surprised to see him succeed.

We had an unforgettable evening at Zwanzig23! Lukas and the whole team are such wonderful hosts – warm, welcoming, and genuinely taking the time to talk with their guests. The atmosphere is cozy and inviting, the kind of place where you instantly feel at home. The food was absolutely amazing – bold, rich flavors combined with a thoughtful concept of local sourcing and sustainability. We loved the creative “taste the waste” entrée, which perfectly reflects their no-waste philosophy. Every dish felt both surprising and comforting at the same time. We ended up spending over four hours there, laughing, drinking, and savoring every bite. It was more than just dinner – it was an experience. Thank you, Lukas, for such a special night. We’ll definitely be back!

It was an absolute delight having dinner here last night! Mouthwatering gourmet food presented in a casual, familial atmosphere! Super friendly staff, open kitchen, high-top dining, the chef himself going from table to table for a little chat, it was just amazing. We had the 6 course menu, which took around 3 hours. The vegan, as well as the non-vegan option were delicious, same goes for the alkoholisches and non-alcoholic drink pairing. Unexpected ingredients and combinations delivered in an absolutely masterful creation. We will definitely come back and opt for the 9 course menu next time…not because we were still hungry after 6 (absolutely not the case!), but because we want to try even more of this magic!

Unfortunately, this restaurant did not fully meet my expectations, and I would rate it two stars. Given that it is a one-star Michelin restaurant, expectations are understandably higher than at a casual dining venue. While the food and drinks were very good, the overall experience was significantly impacted by shortcomings in service. We visited as a group of five to celebrate a birthday and were seated at the large communal table rather than at the bar. Regardless of the seating concept, I would expect a consistently customer-oriented experience at this level. Unfortunately, several issues stood out: 1. When we politely asked if the music volume could be lowered slightly to allow conversation, the response from the owner was that the music would remain at the volume he preferred. While every restaurant has its own concept, the tone of this interaction felt dismissive. 2. Our menu order was mixed up. We ordered a combination of small and large vegan and regular menus, but what we received and were charged for did not match our order. After pointing this out, the issue was neither acknowledged nor corrected. 3. Orders for still versus sparkling water were repeatedly confused throughout the evening. After multiple incorrect servings, we eventually stopped mentioning it. 4. We clearly communicated the need for a gluten-free menu with gluten-free bread. The bread was forgotten twice, and it was never clearly confirmed whether all dishes were fully gluten-free, which is concerning for guests with allergies. 5. There were inconsistencies in menu presentation. Vegan dishes were occasionally mixed up at the table, requiring guests to swap plates, and some plates were presented incorrectly. 6. Although English menus are available, we were handed German menus multiple times and had to request the English version more than once. Overall, the evening was disappointing, particularly in relation to the price. While some guests may appreciate the restaurant’s concept and atmosphere, it did not work for us. The idea of chefs presenting their own dishes is a nice touch and shows appreciation for the kitchen. However, improved coordination and professionally trained service staff would significantly enhance the overall experience.

If you’re looking for an authentic fine-dining experience with a family and casual twist, then Zwanzig 23 is the place for you. The whole experience started when we were warmly welcomed, and then surprises kept unfolding course after the other. I definitely had one of the best fish dishes twist ever in there. Every element turned our evening and dinner into an unforgettable experience. Well done and bravo to Lukas and the team!

Amazing experience in terms of food and service. The сhefs are very polite, friendly, and courteous. Dishes are an art and a delight! A couple of things that we disliked: 1. sitting 3 hours on the bar chair is painful; 2. time uncertainty. we didn't know it was going to be 3 hours long and the last hour was hard to sit through.
