Too new to be included in Modica a Tavola is
to be found on Corso Umberto in Modica opposite the Palazzo della Cultura. Excellent food, well made and presented. Not the cheapest eaterie in Modica – expect to pay about 50 euros per head – but it will be a memorable meal.
Also too new is DOMUS on Corso Umberto at 154 – next to the bank. Well priced and a good range of food, especially meat – and open for lunch and dinner. Great reviews on TripAdvisor
