I've been going to the Masa for years. The price is right and I have always had great service.
The food has gone a little downhill recently. The salmon seems to be cut thinner and more raggedy...the sushi not cut in a uniform manner. The tempura is hit and miss. Sometimes hot, crunchy and tasty...at other times flaccid and greasy.
Though the decor hasn't changed in years and needs a little sprucing up, I love the ambience. They have that diffused lighting that makes *everyone* look gorgeous. Great place to meet your blind date...lol!
