A little small. But you know what it work’s now my burger i was a little disappointed!! Cause it was like a McDonalds burger meat only. For a place that specializes in hot dogs burgers an grill cheese. You’d think the burger would be a real burger an not a frozen pattie that’s about as thick as a mcdonalds patty ! I just quess i was expecting a better looking burger than what I got . But all in all it still was alright to eat . Like I said they definitely could get better quality an thicker beef patties. If you have to charge more people won’t complain if there getting a beefy looking burger.not one that you actually got to take top bun of an make sure they didn’t forget to give you the meat patties !!!!¾

Gilley’s Diner in Portsmouth, NH, is a hidden gem for anyone looking for classic diner food in a charming, nostalgic setting. My wife and I stopped by for a quick bite and were impressed by the experience. She ordered a hot dog with fries, and I opted for a double cheeseburger with fries. Both were served within 5 minutes, hot, fresh, and full of flavor. Despite the small menu, the food is top-notch for diner fare, and the friendly service adds to the experience. The diner itself is small and quaint, with only six seats, but the charm of this old food truck-turned-diner more than makes up for it. The service was fantastic—there’s only one person running the place, and she handled everything seamlessly. If I lived in the area, I’d be here at least once a month. Highly recommend for anyone craving a quick, delicious meal in a cozy, old-school diner atmosphere.

Much larger portion than shown, we were starving! The person who runs the place is super nice and is knowledgeable about Gillys! The atmosphere is wonderful. Established in 1912 and is super yummy and affordable!

I arrived as they were closing ! They had run out of bread for 3 people, so we suggested hamburger buns= Somehow, when I ordered a grilled cheese sandwich, they found the last 2 pieces of Bread for me ! ❤️ the 2 lady workers there are phenomenal

This small 8 stool diner is absolutely amazing! My husband and I ate late night (our first time ever) and was greeted by Arlene with a smile who then took our order and then cooked it! We had double cheese burgers add bacon with “everything” , Poutine (was super cheesy and delicious without being soggy) and the chili cheese fries (full of flavor!). Really enjoyed the history and overall vibe of the place. Will definitely be back to check out with our kids 🙂 Picnic Table’s are set outside when the weather gets nice adding more room for service. Take out available but can not call ahead and no delivery services which is understandable for place this size.

Incredible historic burger joint. Also a classic for hot dogs, but IMO the burger (double cheeseburger with everything in my case) is the thing to get! Absolutely worth the stop even if you’re passing through town. Bit of a wait on the Thursday afternoon we went, but considering there was only one member of staff in there, it was impressive being able to juggle taking orders, cook, and serving as well.

Fries first as they take the longest, but who doesn’t like a greasy fresh cheeseburger & simple toppings options with hand cut fries. No thrills, no surprises, no fancy restaurants just old school comfort

I’ve heard so many good things about this place but to me, it was just okay. I wouldn’t go out of my way to order from here. My food was fine but nothing out of this world. The woman taking care of me was so kind and respectful too. It’s a cute place and I am happy I tried it but I probably won’t go back.
