Need holiday lunch rec in CC -- 3 people $20 each

I'm a little stumped. Three of us would like to get together for lunch next Wednesday since our office is not having a holiday party this year. I'm looking to keep things "cheapish" ($20, no alcohol, an entree each with shared appetizer) but with a fun/festive or nicer-than-our-usual atmosphere.

We're right at Broad and Chesnut, so within walking distance would be a bonus. We've been to El Vez and Jones too many times, but something similar would work well. Right now I'm leaning towards Cuba Libre, but I can't remember their lunch prices and it would require taking a cab/bus.

On the other end of the spectrum...How is the bar at Nineteen (XIX)? The decor definitely fits the "nicer than our usual". Can it be done for $25?
