San Diego is a progressive city that offers lots of great restaurants, vegetarian and vegan options too, and no shortage of nightlife! The best areas to spend the evening are the Gaslamp District/Little Italy area if you want moderate to pure chaos, or North Park if you're deeper into the hipster scene.
Parks you might ask? Yupp, San Diego's got that too. Balboa Park is a particularly beautiful park with many sections including several museums, a botanical garden area, and even a dog park nearby! Check out the alluring variety of cacti - stunning!
The public transportation system, which consists mainly of buses and trolleys, does a pretty decent job connecting the different parts of San Diego. Should you decide you want to venture out of the city, train and bus connections will conveniently take you north toward Los Angeles to meet movie stars, or south to Tijuana if you're curious what’s on the other side of the border.
The main takeaway is that although it’s an expensive city, it's definitely a very livable and enjoyable place!
