This chain Italian restaurant was an excellent addition to the Mumbles dining scene. Family friendly with excellent views over Swansea Bay and the Mumbles lighthouse. Prezzo is certified by Coeliac UK for those of us who are forced to avoid gluten and both the kitchen staff and the wait staff are properly trained on allergies and intolerances. Gluten-free food is served with a flag on a cocktail stick so you are sure they are aware, and in 5 years of dining here, I have never got sick. Decent wine list, by Swansea standards at least. Incredibly helpful and friendly staff, though those not from the Principality may struggle with the local accent (an American friend I entertained there asked me if they were speaking Welsh - it was English but the local accent is strong until you are used to it)
