Thin, delicate pasta sheets wrapped around a center of aged Parmigiano Reggiano that's been transformed into a liquid by the gentle heat of the plate—the cheese becomes almost molten, coating each bite with creamy umami. Shaved truffle and a knob of butter finish the plate. Multiple reviewers describe this as the signature dish that's been on the menu for years because nothing surpasses it.
Tips from diners
This is the dish most people come back for. Chef Bowerman has tweaked it minimally over the years because the simplicity is what makes it work—just pasta, cheese, and truffle.
Share the plate at the table immediately after it arrives so the cheese doesn't cool down too much and lose its texture.
A slab of duck breast seared to keep the interior pink, plated with a warm tarragon and grape accompaniment that brings subtle sweetness and floral notes. The sauce incorporates umeboshi (Japanese pickled plum) which adds a line of sourness that cuts through the richness of the duck. This is the kind of dish that shows Chef Bowerman's worldly technique—French in execution, Italian in some elements, Japanese in accent.
Tips from diners
Ask the sommelier for a pairing—the umeboshi sauce deserves a wine that has acidity to match it. The staff are trained to suggest pairings that work with the dish's subtle flavors.
Elegant sashimi-style white fish plated with a small bead of red beet miso, ponzu sauce that brings bright acidity, and crackling fried pepper seeds that add crunch and a gentle heat. The dish bridges Japanese and Italian sensibilities, with the fish treated with Japanese care and the condiments adding contemporary flair. A light, refreshing option that shows restraint and technique.
Tips from diners
The quality of the fish matters enormously in sashimi-style dishes. Trust that the restaurant has sourced pristine product—this isn't a dish where they cut corners.
Finely minced or nearly sliced raw beef dressed with a precise balance of capers, fine celery brunoise, salt-cured anchovies, and shaved aged Wagyu bresaola layered on top for extra umami. The preparation is French but the ingredients are Italian, showing Chef Bowerman's ability to work across traditions. The tartare itself tastes clean and mineral, the cured components adding complexity.
Tips from diners
Request to know the source of the beef—this is not from a standard supplier. The restaurant sources premium cuts, and knowing the origin adds to the experience.
A clever twist on Roman tradition—the ravioli case is delicate pasta filled with the guanciale, tomato, and pecorino combination that defines amatriciana, finished with a crispy guanciale crisp on top and a light sauce on the plate. The surprise is that the filling already contains the sauce, so there's sauce inside and outside the pasta.
Tips from diners
This is Chef Bowerman's play on one of Rome's four cardinal pasta dishes. Ordering both the Parmigiano and amatriciana ravioli lets you see her approach to elevating tradition.
Glass Hostaria opened in 2004 in a restored former carriage workshop in Trastevere, with Chef Cristina Bowerman at the helm since its inception. She earned a Michelin star in 2010 and has maintained it ever since, pioneering a modern Italian cuisine that respects tradition while exploring global technique and ingredient combinations. The restaurant's commitment to food sustainability has made her part of the Michelin Guide's Green Initiative.
Reservations are essential and often booked weeks in advance. The dining room is intimate, seating only about 50 people, and the restaurant honors a single seating per night during dinner service.
The tasting menu is the way to go if offered—Chef Bowerman's vision is best experienced as a progression rather than à la carte choices.
The wine list focuses on Italian producers, many from small-scale operations. The sommelier knows the list intimately and loves suggesting unexpected pairings.
