In terms of quality at good happy hour prices, I give Sakana 4 stars. It is not the best sushi I have ever had, however I go here frequently with girl friends for happy hour because the sushi is good and we can get out of there full under $30 each, including beer and/or saki.
I recommend trying the flavored wine, it is surprisingly tasty. The service is always good and I am always greeted with a smile. At my last visit, the manager thought we hadn't left a tip and came outside to ask up if there was a problem with our server so that she could make sure that we were satisfied.
This place definitely cares whether or not you enjoyed your dining experience.
