We're meeting some relatives on a Sunday in December at 18th St. & Park Ave. South, and want an inexpensive but good place to eat. It should be not too loud since we will want to chat. I suggested Duke's, but that did not receive an enthusiastic response. Italian food or classic American would be good. (America is not ideal for conversations.) Someone suggested I Trulli or Tarallucci e Vino, but I thought they might be pricey ($40. a head or more). I was looking for a place that would be about $25. p.p., not including drinks.
