SCOTTSDALE—(Globe Newswire)—April 8, 2010 — Kona Grill, Inc. (Nasdaq: KONA), an American grill and sushi bar, today released preliminary sales results for its first quarter ended March 31, 2010.

For the first quarter of 2010, restaurant sales increased 8.2% to $21.1 million from $19.5 million a year-ago, including a decline in comparable restaurant sales of approximately 2.5%. During its fourth quarter conference call, the Company had previously guided to restaurant sales of $19.4 million to $20.4 million for the first quarter. The quarterly comparable restaurant sales decrease of 2.5% compares to a 9.6% decrease in the prior year period and an 8.1% decrease during the fourth quarter of 2009.
