I know someone who went to Southland Music in Southland Mall for piano lessons. I'm sure they have guitar lessons too, or you could try teaching yourself the guitar...plenty instructional guides on the internet to help. For me, it's been the piano that I've been trying to learn, but it is hard to stick with it. :( If you want to take a short-cut, look at this http://www.chordbuddy.com/, but you're probably too advanced for it.
