The native oak trees in this city became the basis of its name. Nowadays, oak trees are not the only ones blooming here. A blossoming of rich culture is also made possible by the immigration of different ethnic groups. Hence, you can expect gastronomic treats from countries like Ethiopia, Thailand, Mexico, and Italy. The formerly manufacturing-heavy city has also transformed into a trendy handicraft lover's paradise. On the more outdoorsy side of things, Lake Merritt provides a good natural playground for boaters, kayakers, and bird-watchers. Jack London Square, on the other hand, features restaurants set amid a picturesque waterfront setting.
