My family has been going to Napoli's for 40 years, and every trip is a pleasant reminder of why. The magic they work in this unassuming little building is an absolute treasure to this town. Most Vallejo natives, including myself, know the quality of their food. To this day, I have yet to find pizza that holds a candle to this. When others ask for a recommendation, Napoli's is the first name to come to mind.
This is how pizza should be done folks. Everything from the fresh vegetables, perfectly cooked meats, all the way down to their marinara sauce is top-notch. Do you like melted, gooey mozarella? They have it in spades. Perfectly crisp dough? They have that too. In addition, they have a great selection of sandwhiches, my favorite being the chicken parm. Everything about this place embodies quality, and their years of experience does not go to their heads. When you enter, the staff immediately greets you and makes you feel welcome. They are never too busy to treat their customers right, which is sadly becoming a scarce practice. Other restaurants need to follow Napoli's example. No matter where I travel, this will always be the gold standard by which I compare.
If you're visiting Vallejo or just passing through, you NEED to try this place. I'm sure you won't be disappointed.
