I'm up near the Belmont El quite a bit -- and here are few I love to go to:
Mi Tierra (cheap decent mexican with a festive atmosphere and good drinks -- and some tasty salsa!)
Jack's on Halsted (at Halsted and Belmont) a little more upscale in price but not a bad dinner at all)
I also like Pizza Capri -- which is right at the corner of Sheffield and Belmont -- it's not going to win any awards but it's kind of cute and inexpensive and the food I've had there was surprisingly good. It's perfect for a casual get together.
There's also Clarke's -- which is primarily a breakfast joint but also serves liquor and has a decent sandwich/entree menu. It's definitely a diner but again, a great casual and inexpensive place to eat.
