I'm finishing up graduate school in a couple of weeks, and my parents want to take me and my friends out to celebrate. There will be about 10 of us. Any recommendations for a place to go on the Upper West Side/Morningside Heights area? Nothing too fancy or adventurous, just good food and a nice atmosphere. I'd say we'd be looking for entrees to cost around $15-20? And my dad's not a big fan of Mexican food, so that's out. Thanks in advance for advice!
