Ontario travel tips
Try the best spaghetti in Ontario at Vince's Spaghetti
Family-run Vince's Spaghetti at 1206 W Holt Boulevard in Ontario is a must for you if you have a good appetite. According to the legend, Frank Cucci's uncle started this restaurant as a six-stool open-air French dip stand in 1945. He tempted passersby with great flavours. Now, spaghetti with meat sauce is a locals' favourite Italian meal here.
