Will you find an unfried vegetable? No, but you will find food to appease the most finicky kids and angriest of hangovers along with the friendliest staff and practically pre-covid prices. Just be sure and bring cash!

This picturesque diner was amazing! The iconic slinger was a hit with my husband! I really enjoyed the chili mac. The chocolate malts were a perfect addition. The staff was friendly & attentive. We will definitely be back & bring the whole family this time!

Good old fashioned American diner. I ordered the "Slinger" and it was the perfect St. Louis experience!

Fresh food, quick & friendly service. I always have a good time when I come here. Fast turnaround, and there always seems to be a good crowd eating. Small menu but that doesn't mean it's not tasty! It is cash only though, so come prepared. 10% surcharge on takeout orders too. My dad likes the hangover skillet and I usually get a cheeseburger. Good prices too! Is it the best burger you'll ever have? Probably not, but all of the other qualities make it great for me.

Courtesy Diner is the best quick diner food you find in the North Hampton area. The food is delicious and the pancakes are surprisingly one the best I've had. All of the servers are friendly and efficient. The restaurant brings in a typical diner-crowd but it's an overall great atmosphere. My only complaint is that it's cash only so you have to be prepared for that when you come.

My wife, daughter and I went here after a recent evening event at the nearby Science Center. I had the slinger, my daughter a chili cheese burger and my wife had a cup of chili and cheese fries. They had just recovering from a rush of customers when we arrived, but they welcomed us, and came by promptly to get drink orders and see if we had any menu questions. A few minutes later they took our order, and food was out pretty quickly. They prepared the eggs on my slinger exactly the way I asked. They checked on us a few times but not too often. We enjoyed the meal, paid with cash and had some pleasant exchange as we were checking out. I'd definitely come back again.

If you love a greasy spoon hole-in-the-wall as much as I do, you'll love Courtesy. It's nothing special to look at, but it's always fresh food accomplished by a surprisingly nice and friendly staff. My favorites include the chili (with or without a tamale and/or spaghetti), the hamburger, the fries and the bacon and egg sandwich on toast. My son absolutely inhales their hashbrowns. Their grilled chicken sandwich is pretty decent. They used to be open later and even 24 hours, but I guess they've been hit by the economy like everyone else has. I always forget how much I like it here until I eat here the next time.

This place is amazing! Great greasy diner food, so cheap. Big fan of the Hangover. The country fried steak is delicious and the gravy is perfection.

Tired this place for brunch on a Saturday morning and it was so good. We got mozzarella sticks, chicken tenders, and the chili burger. The mozzarella sticks were 10/10. They taste fresh and we're super cheesy. My chicken tenders were okay, nothing special. I like my chicken tenders super crust and these had a thin layer of crust. Both of the entrees came with fries and they were not very crispy. For the price the quality is unbelievable. Warning, they only take cash! But there's an ATM if you forget.
