The general consensus of 3.5 stars is about right for Jade. That's exactly what I'd rate them if it were an option, but a 3 is too low when you factor in their excellent service, great atmosphere (indoor and outdoor), and timeliness (esp during lunch when most of the customers have to get back to work). Plus, there really aren't too many better sushi spots in town and Jade is probably the best in Ballantyne.
I've only eaten one non-sushi item and... well it sucked. Even though the server told me it was a good choice. But some of their sushi is pretty good. My favorite is The Rescue roll - I can't remember what's on the inside (spicy tuna I think), but it has fresh White Tuna and avocado on top drizzled with some kind of spicy mayo. It's the reason I keep going back (but if I didn't work in Ballantyne I honestly probably wouldn't). When all is said and done - The Terrace Cafe is the best restaurant in The Ballantyne Village.
