@Cvetan Thanks for the comment!! I am not sure that I'll ever find the same kind of hamburger that my dAd makes but here's a little more to add to the mix. I read this review of a hamburger on this Peace Corps Volunteer's blog about a <a href="http://sofiqm.wordpress.com/2011/11/19/shimmy-shimmy-ya/" rel="nofollow">17 leva hamburger</a>. She claims it's well worth it. I don't know. That seems a little crazy. But maybe it's worth checking out. It's at Concept Cafe and Restaurant (12 Ivan Vazov Street).
