I appreciate meat. But Green's makes it easy to appreciate other things too.
This is one of the only places I've ever been where the mock meat doesn't require a desperate stretch of imagination to replace meat. The dishes are tasty, and some are delightfully cheap.
I would especially recommend the soups. Their hot and sour is very good, and their noodle soups are amazing value (~$4 for enough food for two meals... that's $2/meal!)
The servers also make a point to be polite and friendly, which is rare in cheap Chinese restos but certainly welcome; decor is likewise nicer than average (no white garbage bags "tablecloths")
Food vs price: 5/5
Service + ambience: 4/5
I will be back repeatedly for a cheap, reliable source of vegetarian food.
