Antica Hostaria Romanesca is a no-frills, old-school Roman trattoria in the historic center, so expect classic dishes like cacio e pepe, carbonara and saltimbocca done in generous portions and a slightly touristy but authentic vibe. You should book ahead for dinner, especially on weekends, and be prepared for a cozy, bustling dining room and relaxed service that takes its time. Menus are likely available in English and prices are mid-range for the area, with cash accepted but cards usually fine; tipping is small and optional. If you have dietary needs, mention them when ordering since the kitchen is traditional and may need to adapt.
