There is a very good Vietnamese restaurant on Winchester near Santana Row called Asia Moon. Yummy Fresh Rolls - garden rolls with Ahi tuna or shrimp, mango, cucumber, etc. The Crescent Moon crepe is great- egg crepe with pork and shrimp served with lettuce, cilantro, mint and basil.
This place seems quiet despite the great food and prices, probably because its across the street from the Santana Row action. We're rooting for it to do well.
Highly recommended for an afforable dinner. We had a great meal for under $30!
