About this venue

Step beneath the twinkling canopy of Larimer Square and descend into Osteria Marco, a subterranean sanctuary where "Italian soul meets Denver history." Named after Chef Frank Bonanno’s youngest son, this refined yet playful venue specializes in artisan craftsmanship—from house-made burrata and hand-cured salumi to wood-fired pizzas. With its grand staircase, walls lined with hundreds of Italian wines, and a warm, low-lit ambiance, it is an idyllic setting for rehearsal dinners, chic welcome receptions, or intimate wedding feasts. Osteria Marco offers a romantic, hidden-gem feel that captures the essence of a lively Italian tavern right in the center of the city.

Osteria Marco

Artisan Italian elegance beneath historic Larimer Square.

The venue’s interior is a masterclass in industrial elegance, featuring exposed brick, rustic wood accents, and a vibrant open kitchen where guests can witness the artistry of cheese-making. The Wine Room offers a semi-private, high-vibe experience, separated from the main dining floor by floor-to-ceiling wine racks that create an intimate, "cavesque" atmosphere. For complete seclusion, the Tavern Room features sound-buffering sliding panels, providing a quiet, polished space for heartfelt toasts and private celebrations. For those dreaming of a grand urban affair, a full restaurant buyout allows guests to flow from the sleek bar to the charming outdoor patio nestled under the historic street lights.

Wedding Party
We hosted a large group dinner here a few days before our wedding, and it could not have been a more perfect start to the celebration. Planning a meal for a big wedding party can be stressful, but from the moment we walked in the team made everything feel effortless. We opted for family style service, which was the best decision. It allowed everyone to try a bit of everything. The charcuterie board was a showstopper, the Bolognese was rich and comforting, the meatballs were tender, and the wild mushroom fusilli was very creamy. All in all I would recommend this restaurant for large groups because of how well everything went with my party.

Osteria Marco is truly a gem in the heart of LoDo. Not only is the food outstanding and delicious but the staff is great!!! They are so attentive and kind! During my last visit I hosted a large party and we started with the Burrata, which was to die for, and shared the Bolognese, Bucatini Carb, Marg Pizzas, and ended the night with the Chocolate Bombs. We were greeted with complimentary bubbles, and ended the night with complimentary house-made limoncello. If you get the opportunity to stop by this gem, consider yourself truly lucky!
