I'm a Home Brewer, so I like to taste beers without spending an arm and a leg. I like to go to Home Brew Mart to get my supplies and enjoy sampling the Ballast Point Brewing beers on tap. They share the same space.
I also like to check out the brews at the Firehouse Brewing Company near the Stadium. They have reasonable prices, a bit meager on accomodations, but it is a great place to hang in the sun with some good company if you are in the neighborhood.
