Hungry after a couple of intense hours of boot camp, we walked up to Mainland Street's restaurant row for supper but did not get very far. My dinner companion confessed that since his last visit here he had been craving for a repeat meal of the sushi burger at Hub Restaurant. So that's where we went.  The Sushi burger consists of sesame crusted albacore tune loin with a wasabi soy mayonnaise, cucumber avocado, lettuce  and a soy chili dip. There is a choice of side house or Caesar salad or fries.
