"Green" has recently opened & is already a favorite with local vegetarians. My vegan brother and sister-in-law who live in SA invited me to lunch there today, and I was favorably impressed. This casual restaurant is in a beautifully remodeled old house in a funky neighborhood just outside of downtown (maybe a 5 min taxi ride from the Riverwalk hotels). The menu is large and varied, with many vegan options (and the staff will make vegan versions of many vegetarian entrees). The daily specials are creative, the coffee is free-trade organic, and the desserts are all vegan. Prices are very reasonable - lunch for 3 with appetizers, main course and coffee was about $30. Portions are large - we were too stuffed to try the vegan chocolate cake. Green doesn't have a liquor license but customers are welcome to bring their own beer or wine. They are considering supplying wine glasses, etc. for a small corkage charge.
Green is open for breakfast, lunch & dinner, and does not close between services, I suspect their coffee bar and free WiFi draw customers all day. It has already won strong support from the local Vegetarian community - my family has eaten there 4 or 5 times in the past couple of weeks, and they have friends who have eaten there every day since the cafe opened!
Green is at 1017 N Flores, San Antonio, Tx 78212
