It would be rude to go to Hamburg and not look for a decent hamburger. Burger Lab came up on several lists for best burger in the city, and rightly so. We tried the Classic and Bacon-BBQ, splitting a sweet potato fries between two of us with some extra BBQ sauce. The burgers were excellent - notably the bun didn't disintegrate as we worked through it, a mark of a quality burger. The sweet potato fries and homemade BBQ sauce, however, were some of the best I've ever had (though one portion between two was more than enough). Despite it being somewhat hidden away from the city centre, it's definitely worth journeying out for.
