I'm surprising myself giving Nook Cafe a 4. It only offers basic things like salads, sandwiches and pizza as well as coffee, but it works for something quick to eat. The food is expensive given it's just a cafe, around $10 for a salad and $6 for a slice of pizza, but that's more or less what you'd find elsewhere along the Strip. The staff here are super friendly and cheery!
I got a slice of margherita pizza for $6, which they heated up for me in their wood-fire oven. The slice was actually pretty big and reasonable for the price and surprisingly good. The crust was thick so the slice held itself up pretty well despite being rather large. I usually prefer super thin crust pizzas, but their thick crust was soft and chewy. I'd definitely recommend eating the pizza while it's still warm and the cheese is still melted! I took mine to-go and only had a few bites of warm gooeyness before the cheese started to harden :(
