About 420
Housed in a renovated 15th-century Gothic building directly opposite Prague's Astronomical Clock, 420 is the more accessible sibling to Michelin-starred Field, helmed by chefs Radek Kašpárek and Marek Kominek. The restaurant delivers contemporary Czech cuisine with a Gault & Millau 15/20 rating, featuring an open kitchen, in-house bakery, and charcuterie crafted in the Gothic cellar beneath soaring, cathedral-like arches capped by a striking glass roof. Named after the Czech international dialing code, it's become a destination for those seeking refined local flavors without the formality—think elevated goulash, duck pâté, and inventive desserts in a space that honors both medieval grandeur and modern culinary craft.
Good to know
Request seating in the central hall beneath the glass roof rather than outside—the atmosphere is infinitely more refined, and you'll escape the throngs gathered around the Astronomical Clock.
The chef
Radek Kašpárek, Marek Kominek
Radek Kašpárek and Marek Kominek bring their experience from Field, the Michelin-starred Prague restaurant, to this more relaxed yet equally ambitious venture. Their approach centers on contemporary Czech cuisine that respects tradition while embracing modern technique—focusing on quality sourcing, house-made charcuterie, and in-house baking that grounds the menu in craft. The duo's philosophy bridges the gap between fine dining rigor and approachable Czech soul, evident in everything from their fermentation program to the open kitchen's transparent mise en place.
The Insider Compass
Four dimensions, each assessed independently against the same criteria everywhere we rate.
Plate
The kitchen delivers contemporary interpretations of Czech classics with serious technique—lamb with garlic, rich beef goulash, and house-made charcuterie showcase quality sourcing and thoughtful execution. Portions are hearty and richly flavored, balancing refinement with the soul of traditional Czech cooking, while desserts demonstrate genuine creativity and precision in both composition and plating.
Vibe
LivelyThe central hall beneath the glass-roofed Gothic nave offers a dramatically more relaxed atmosphere than the tourist-heavy exterior seating, with stylish lighting and curated music that elevate the mood without overpowering conversation. The open kitchen adds energy to the dining room, where the crowd skews toward serious eaters seeking a polished yet unpretentious experience in the heart of Old Town.
Service
The team runs a professional, knowledgeable brigade that explains each dish as it arrives, striking a balance between attentiveness and allowing diners space to enjoy the meal. Staff demonstrate genuine warmth and care, offering thoughtful recommendations on wine pairings and navigating the menu with confidence, though pacing can occasionally lag during peak service.
Setting
The 15th-century architecture provides a stunning backdrop—soaring ceilings, exposed Gothic elements, and a dramatic glass roof flood the space with natural light while preserving the building's historic soul. The open kitchen and visible fermentation displays add a contemporary layer to the medieval bones, creating a setting that feels both reverent to Prague's past and firmly rooted in modern gastronomy.
These four dimensions are a handful of the attributes we review. The Insider Rating also draws on research the compass does not display — among them the wine programme, the size and quality of the cellar, the location, and how long the house has operated. It is not an average of the scores above.
