D & A's is my go-to place for ice cream in Oakland.  Although it's not the best ice cream I've ever had, they have the best regular non soft-serve ice cream I've had in PGH to date.  Like other reviewers, I definitely recommend getting the waffle cone--it's delightfully crunchy, light, and sweet, not to mention freshly-made.\n\nIn terms of flavors, I'd recommend the chocolate chip cookie dough and the birthday cake.  I wouldn't call myself a huge cookie dough ice cream fan, but I really enjoyed their version, due to the high cookie dough: ice cream ratio.  I was skeptical about the birthday cake flavor, but I tried it out of curiosity, and it was great!  It has sprinkles, frosting, and cake all mixed together.  Try a sample if you're uncertain (that's what I did), but I think you'll like it! 4.5 stars.
