"This reliable chain has beckoned late night warriors with the sweet smell of pancake syrup for years. Besides pancakes, IHOP has branched out with burgers, burritos, bowls, and gluten-free options. And for anytime cravings for burgers, fries, pancakes, milkshakes, and more, diner chain Denny’s also does the trick. D.C. is home to two 24-hour Denny’s outposts (both in Northeast), plus two in Maryland (Laurel and College Park) and one in Virginia (Falls Church)." - Eater Staff
