Italian bistro food with attentive, professional service. I was concerned that Mario's would have a cafe vibe, but in the evening, there are white tablecloths and a much more bistro feel. We were accommodated quickly even though the restaurant was almost totally full. We felt welcome and the food we ate was tip top quality cooked well. I really enjoyed the chardonnay - I'm not usually a drinker of white wine but it was a warm evening and chardonnay was just the perfect tipple. The gluten free dessert was extraordinary. Sweetened with dates, it made such a wonderful change from a chocolate brownie - if you know, you know.
