Strong World Cup viewership bodes well for the chain's same-store sales performance this quarter and next, according to a new Wunderlich Securities report.

The firm's channel checks revealed "standing-room-only attendance" for last night's game along with "long wait times (over an hour) for any tables for viewership in either the bar, dining room, or patio" at the restaurants' locations.
