No need to be grumpy--the late-night waiters are often gruff enough for two. But that's part of the charm at this sticky-tabletop landmark in the heart of Bethesda. We'll never tire of the $2.50 grilled-cheese sandwich, buttery and crisp with a simple slab of American melted inside. A side of fries ($1.50) was a post-drinking dream.

You can eat breakfast all night--the place doesn't close--and it's hard not to order a creamy milkshake ($3.50) to sip while you scarf down your $6.50 chicken tenders.
