GasLamp District San Diego is the center of San Diego nightlife. It's between Broadway and Harbor and between 4th and 6th Ave and you'll find a LOT of great bars, live music, restaurants, clubs, lounges and events. For Sushi hit Taka on 5th Ave and then head to Tipsy Crow between F&G streets to dance all night to great music (everything from 90's hip hop to top 40 and even some cool flip tracks). Any given night there will be live music so you might just head in when you hear your flavor. There are several hotels downtown but if you want a cool timeless hotel with old-school charm but new appointments, you'll love the US Grant. And don't forget to hit the beaches to get your tan on!!
