I was severely disappointed with this particular Osaka. I absolutely love the one on Sahara, and wanted to give this branch a try. I definitely regret it. At lunch time, there were only three parties when there should have been a large lunch rush - and for good reason. The service was slow, extremely, extremely slow. It took about 20 minutes just to get our first sushi roll. The bento boxes we ordered were overpriced for what you've served, and half of it was cold by the time it got to our table. I will not be visiting the Summerlin Osaka in the future, and instead will stick with the Sahara Osaka, which has fast service, better prices, and is overall excellent, quite the contrary to this branch.
