By far my favorite night club in dc!!!
Always great music, great pizza, great people.
My partner and I came for the jumbo slice, and we stayed for the greatest 2010s playlist. During our ten minute wait, we were already served an amazing musical meal.
If I could put more than five stars for the atmosphere I absolutely would.
Pizza slice size is also proper, could easily be the size of a small full pizza.

Don’t order delivery from this place. Poor customer service when we called to check on our order since we did not get an update and it was past the delivery window we got. The order was completely wrong. The pizza was barely cooked with raw dough. The chicken was old and stale and not properly cooked. Really disappointed across the board.

So we ordered late last night, I got the buffalo slice and my wife got a cheese slice and add pineapple. So apparently the base of my buffalo pizza was tomato base… wth is that. Then my wife slice shows up burnt and no pineapple. Worst $30 I’ve ever spent on pizza. I’m from NY where I follow this company from sm so I came here to go, visit my grandfather and arlington cemetery. On my six year wedding anniversary. Safe to say if and when I come back it won’t be for this pizza. ( Also, we couldn’t get a hold of anybody last night to fix our situation)

We visited this week after many years not coming and the pizza still the best pizza since we 1st found this place back in 2009. The gentleman working in the counter, he is Hispanic, still working there for many years gave us the best service. This is the best Pizza in the area. We will come back for sure.

Behind the Slice: Jumbo Slice Pizza’s Strengths and Considerations
Discovering Jumbo Slice Pizza after watching a video on DC’s best large pizza slices was a game-changer. Full transparency: the pizza here is beyond exceptional—no notes needed. However, my focus shifts to the customer experience, crucial for out-of-towners. The initial impression is hindered by a visibly dilapidated interior, lacking attention and care. Cleanliness concerns arise, impacting the perceived hygiene of the food station.
Moreover, encountering an individual engaging in inappropriate activities (such as literally smoking crack out of a glass pipe) raises discomfort. It was around 6:30 PM when we arrived to eat so it was a lot to see at such an early hour. While understanding the need for a safe space, establishing conditions for shelter-seekers could enhance the atmosphere. And considering the winter conditions, I understand the need for a safe space, but owners could establish conditions—no drug paraphernalia. The lack of seating and the scent of smoke prompted us to grab our order and leave. Yet, the outstanding pizza, efficient service, and friendly kitchen staff can’t be overlooked.
Jumbo Slice Pizza has significant potential with its phenomenal pizzas, straightforward menu, and nostalgic 90s jumbo slices. However, a strategic investment in a well-maintained storefront is crucial. The perfect combination of jumbo pizza slices and a charming interior could evolve this phenomenal pizza spot to dominate as THE pizza spot in DC.
For those seeking the perfect jumbo pizza slice in DC, Jumbo Slice Pizza is a 5/5, but the atmosphere is a 1/5, with hope that some tough love will be given to truly elevate and match the food.

This place is awesome! Reminds me of real NY pizza – doughy and greasy and cheesy and delicious! You basically have to stand to eat, just a few chairs here and there, but it’s not a big deal. Service is great and quick too!

Fresh, hot pizza with huge slices and great flavor. Fast service and always satisfying. Came sober and it was still amazing – the best jumbo slice pizza in DC

I will be reaching out to the DC health department recommending they do a full inspection of this place and how they do service. When I came here on December 27th 2025. I asked for a cheese jumbo slice and was given a box immediately which was a bit suspicious. Then I opened the box and bit into the jumbo slice and it was completely cold. The owners of this establishment should be ashamed of how they run this business.

The pizza itself was very good. I couldn’t give 5 stars because no hand sanitizer was available and not restroom to wash my hands before eating. When you walk up, you may question if the place is even open at first sight but once you order and bite into the pizza, you’ll be glad you came. I will come back next time I’m in D.C.
