I live super close to LGO, and come here regularly for coffee and sometimes breakfast. This place has a great vibe and super good coffee (there are lots of fair trade and organic options). The grapefruit sunrise juice (grapefruit and pomegranate) is also amazing. So for food and coffee, LGO gets 5 stars.
Downside: on the weekends, this place gets PACKED. Because there is so much merchandise inside, it is almost impossible to move between all the people and stuff. The staff gets cranky, too. I mean, a smile would be nice!
The coffee cart outside is a great option if you know what you want to order and want to avoid the crowds. There are even some cute picnic tables by the cart if you want to stick around to enjoy your food, and the servers outside are always super pleasant.
Before you leave, check out the wine area. I love to peruse a cute wine shop, and LGO has a fun selection.
