In contrast to the classic dog on a bun, which Tommy's also offers with all the usual fixings, the Italian hot dog ($5) deposits onions, peppers, potatoes, and weiner in a half-moon of "pizza bread." Neither pizza crust nor pita, it's something like Italian bread without crackle in the crust, and its bulk overwhelms a single dog. For a few dollars more, a double or triple, perhaps in combination with a housemade split-grilled pork sausage, would put the protein in better proportion.
Side note: I don't think ketchup belongs on hot dogs. But given the plentiful buffer of potatoes, many of which I picked off with a skinny wooden fork, this wasn't an issue.
