Corner Bistro in the West Village was one of my first big "discoveries" after moving to NY and is a place I've brought many out of town friends to over the years. They also have an LIC location now and I think it's time we check it out!
In addition to the "Bistro Burger" - my personal choice for best burger in NYC - they also serve BLTs, Grilled Cheese and Grilled Chicken sandwiches, and yes, even salads. In addition they have very affordable beers on tap, including $3 McSorley's and McSorley's Dark. So basically, we have all the makings of a fun Saturday afternoon!
