The Junction Cafe in the San Antonio Valley is the only place to buy food between the Lick Observatory on Mount Hamilton and Livermore. San Antonio Junction is at the intersection of Mount Hamilton Road, Mines Road, and Del Puerto Canyon Road at -121.4908 37.3919.
The Junction Cafe features an eating area outside and several hummingbird feeders on the front porch. There are frequently several Anna's hummingbirds feeding at once. This is unusual since male Anna's hummingbirds are very territorial.
