Terms of Service

Last updated: June 2026

These Terms govern your reservations, catering orders, and visits to Mamma Mia — an authentic Italian restaurant with two California locations in Riverside and Fullerton. By making a reservation or placing an order, you agree to the terms below.

Reservations

Reservations at our Riverside and Fullerton restaurants are confirmed upon receipt of confirmation. We hold tables for 15 minutes past the reservation time. For parties of 6 or more, a credit card may be required to hold the reservation.

Cancellation Policy

Please notify the restaurant at least 24 hours in advance if you need to cancel or modify your reservation. For large parties and private Italian dining events, 72 hours notice is required.

Catering & Private Events

Italian catering orders require a minimum of 5 business days notice. A 50% deposit is required to confirm catering orders and private dining bookings. Final payment is due 48 hours before the event.

Dietary Restrictions

Please inform us of any allergies or dietary restrictions when making your reservation. Our kitchens handle wheat, dairy, eggs, and tree nuts; while we take care to accommodate requests, we cannot guarantee a completely allergen-free environment.

Gratuity

A 20% gratuity may be added to parties of 6 or more. For private events and catering, service charges will be discussed during the planning process.

Dress Code

Both Mamma Mia locations maintain an upscale-casual dress code. We ask that guests refrain from wearing athletic wear, flip-flops, or overly casual attire.
