Sunday brunch lines at Jam on Hawthorne (2229 SE Hawthorne Blvd., 234-4790) stretch a full block, but seats are plentiful at weekday happy hour. This is odd, because the bar offers insane deals from 5 to 8 pm. Take the $5 half-pound breakfast burger topped with a fried egg, bacon and cheddar—it's every bit the equal of Slow Bar's burger but at half the price. Or the excellent $3 hummus plate with olives, cheese, tomatoes and greens. Paired with a $1 tall boy, Jam's happy-hour deals are the best cheap dinner around. This cavernous breakfast joint does have a proper bar (with sugary mixed drinks for $7), though the lighting isn't quite right for a lounge and evening music wanders too far into '70s funk. Those are tiny quibbles when your mouth is full of a Stella Blue Burger. This glory is probably fleeting. Enjoy it now and expect lines or price hikes soon.
