First, let me share my credentials. I was an American Field Service student in southern Italy, so I am very familiar with the cuisine as it is prepared in its home country. Giovanni's, as its owner was proud to declaim, and truthfully so! - is food "like Nonna (that's "Grandma" for you non-Italian speakers) makes." Our bruschetta was a flavorful topping of tomatoes, spices, excellent olive oil and garlic on delicious Italian bread. My dining partner's chicken parmagiana was not the over-breaded, microwaved concoction that has given this dish a bad name, but fresh chicken, excellent Parmesan, and fresh tomatoes cooked into a slightly spicy sauce. My veal marsala was tender and the sauce was light and not (unlike some places) sweet. Our pasta was al dente and the tomato sauce adorning it redolent of the fruit from whence it came. The owner recommended a delicious red wine that complemented the meal. He has an excellent knowledge of Italian wines and a very good selection, moderately priced. For dessert, we shared the homemade cheesecake. If you enjoy a New York-style (not too sweet) cheesecake, you will be very happy with this, as we were.
I think the reviewer who alleged that this restaurant had slow, unfriendly service must have confused this place with somewhere else. The waitress and owner welcomed us immediately with a smile. Both were helpful concerning the menu items, even though the restaurant was very busy (all but two of the tables were occupied at 7:30pm on a mid-week night). In fact, the owner frequently checked the patrons at each table to see if they had any needs, questions, or additional menu desires. A patron sitting at the table next to ours shared her dietary needs with the owner. I overheard him say that he would be happy to change the sauce to be served with the sea bass, which was one of the specials for that night.
While the restaurant is tiny, the tables are not jammed together. The thermostat was at a moderate temperature (all too many places turn their A/C to 68F or worse; the sweaters we brought in "just in case" were unnecessary).
When I return to Greenville, I will be delighted to dine here again.
