Jess and I are all about the shrimp sauce too, but Osaka has done a great job of getting it dialed in. I definitely recommend you try it out anyway. Dinner for 2 for under $50 with a coupon at valpak.com (not counting drinks and 2.95 per person for fried rice [effing redonkulous, but it rocks]) is tough to beat, especially at Benihana.
