Construction begins at the end of this year, with spring 2009 penciled for the grand opening. The lease has been long rumored in brokerage circles, but the concept and the final plan has just been sealed, according to Celeste Fowden, vice president of CB Richard Ellis in Dallas. She, CBRE senior vice president Dennis Barnes and Malcolm Ross, senior director of GVA Cawley in Dallas, represented co-owners Moinian Group and SMA Equities, who bought the 33-story building in April 2007.

Pyles, whose signature restaurant is at 1807 Ross Ave., is taking 2100 Ross' Olive Street and Ross Avenue corner, leasing space now holding the management office. The keystone location was picked because it abuts a practically ready-to-go outdoor terrace that will be outfitted with 35 seats for customers. Samar's interior will seat 60.

Pyles' partners in the new restaurant are George Majdalani and Michael Welch. The high rise has two other restaurants, but as chains they can't compare with the drawing power of Stephan Pyles.
