I will be in San Diego for work in early April. My girlfriend is going to come out for a few days after I am done. I have been to San Diego several times and will have just spent a week there. I am thinking I would like to get out of town a bit for at least a day or 2. I am looking for some good ideas for fun things to do in the area. Any good ideas?
What dates? The Padres are home for much of April; even if you're not a huge baseball fan Petco is a great stadium and I'd put Petco's food and micro-brew selection up against any stadium in MLB. If "early April" means the first week, the season opening series against the hated Dodgers is an awesome way to spend an evening.
I can recommend restaurants if you like to eat well, and a few dive bars, but I'm not a club guy these days so maybe Maurile can help there. There are tap rooms everywhere - I highly recommend the Ballast Point Tap room in little Italy if you like their stuff. They often have 4-5 different versions of Sculpin on tap that they don't bottle.
What's your music genre? Belly Up in Solana Beach is the best local venue in the area, IMO. There's a House of Blues downtown. The North Park Observatory has been getting some really great talent lately. Sleep Train Arena in Chula Vista gets a lot of larger bands that can draw 10k+. Lots of smaller venues as well if your tastes are off the beaten path: google Casbah, Winston's OB.
