Bellacino's overall has pretty good pizza & above average subs, & you sure do get a large "grinder". Their grinders come loaded with toppings & are absolutely huge. And don't get Subway sizes mixed up in your head with Bellacino's, because if you order a full size grinder you'll be in for a shock. It's right around 20", with the half grinder around 10". Also, all of their grinders are over toasted so expect a crispy crust unless you specify otherwise. They have some pretty diverse grinder options to choose from, but you won't be too thrilled if you love to customize (they only have a few options there).
Outside of the grinder realm, their pizzas are pretty good & greasy. Nothing too great though, but not too bad for the price & size. This is their other specialty based on their namesake, but I'd definitely choose grinder over pizza here. They do have other menu items, but I've never ventured into that realm.
