So I might be biased coming back from Seattle, WA back to Phoenix, AZ, where there are few places that stay open past midnight, let alone places that will do PostMates deliveries that late in the day.
I ordered the Belgian Waffle Slam, which is a whole waffle, served with a couple sausage links, eggs cooked to your style of preference, along two strips of bacon.
The food is good to the extent of what you'd expect out of a Denny's.
Knocked a star because the wifi here is terrible; the business applies throttling on individual connections despite there only being one customer in the building at the time (me). Would not recommend setting up your laptop at this Denny's despite the restaurant being in a good part of town.
