Sunday Lunch for 15

I'm looking for a place for a baby dedication luncheon this Sunday for a group of 15. Preferably near LaSalle and Chicago, or between there and Bucktown. Want to keep it near $20 a person. Just looking for any ideas. Thanks.

$20 per person won't quite get you lunch at Fogo de Chao or Brazzaz (search for threads by name or "Brazilian Steakhouse") but they certainly have the table size and good vegetarian options if that's important.

Grand Luxe Cafe is a possibility (and the perennial answer to the oft-asked question on economically seating large groups in the Mag Mile / Near North area). It's less divisive here than Weber, Ben Pao, Cheesecake Factory, and other 'shiny' chain spots. Threads on all (and on general group seating in the loop) can be found by using the search function with the "find all terms" button selected.

Cafe Iberico is right at LaSalle and Chicago, and is certainly within your price range. They are open on Sunday at noon. I don't know if Tapas fit the bill, but they are usually a fun group meal (everybody can find some things they like). I have not been there for a long while, so I can't specifically make a comment about the food. I know Iberico has garnered some mixed reviews lately.

Club Lucky has a private room, that would be great. I had my rehersal dinner there for 30.

We've had a few Sunday family afternoon parties at Greek Islands. They have rooms for different size parties. The service and food always seem to please our guests. Not too far from where you wanted, at Adams and Halsted. Parking is free, with valet service included.
