I'm a big fan of this mall based Denny's in New Lynn. Great any time of day, but especially good for a late night snack after some drinks at local bars. Good comfort food including burgers, pizzas, steaks, and a great range of all day breakfast options including omelettes, pancakes, griddle potatoes. Prices are reasonable - burger meals circa $10 - $15, mains circa $20 - $25, breakfast items from $6 - $14 or so. Often has deals like kids eat free - so check with the restaurant for current promotions.
Serve is lacking and food is not great but I guess you get what you pay for. I do think that when you order tea the should make it for you. I don't want to pay to be give a tea bag and water to make my own drink.
