Jumbo Slice Pizza

Fast Casual · 4.2 (521 reviews)

Jumbo Slice Pizza is a small storefront at 2341 18th St NW in Adams Morgan. Google describes it as a cash-only, unassuming shop known for supersized pizza slices.

It has a 4.2-star Google rating across 521 reviews. Slice size is the main topic. Reviewers mention huge slices that need their own pizza box, pepperoni slices, and the shop's role as a late-night stop after the bars. Several call it a standing-room-only hole in the wall. Opinions on quality vary: some love it, while others describe soggy, floppy slices and say prices have gone up. Parking nearby is tough, according to one reviewer.

It opens in the evening and is closed Monday and Tuesday. Hours are Wednesday, Thursday and Sunday 6 PM–3 AM, Friday 6 PM–4 AM and Saturday 5:30 PM–4 AM. Google lists a wheelchair-accessible entrance, and its website link points to an Uber Eats ordering page. Phone: (202) 248-2623.
