The pizza tastes okay. It's not the greatest pizza on the planet, and their prices are average. It's not much for "New York" style pizza. Their large pizza is HUGE, but their crust is flavorless. Their wings are okay, but not great either.
Their delivery times are off. Sometimes they'll tell you 45 minutes and they'll be an hour, or they'll be 10 minutes early. It's weird. Sometimes they just wont answer their phone. Sometimes they wont tell you when they'll be there. Once, they actually forgot part of my order. In terms of customer service, they're less than stellar... for sure.
Why do I keep eating there? My boss wouldn't eat anything else! I think if I have another Gus's pizza, i'll yack! I would recommend Pizza Hut over Gus's... any day.
