Flip Burger is run by Richard Blais, who apparently was a Top Chef contestant in a season I did not watch. Flip Burger is pretty trendy (long lines of hipsters, bumping club-music) and a large bar with diverse offerings. Flip was recently named one of the Top Ten Best New Burger Spots by Bon Appetit for his experimental burgers. However, being recent burger purists we stuck to the mostly stuck to the more traditional burger offerings. The milkshakes were another story.

It was delicious and a lot of fun, but the overall verdict? Farm Burger in Decatur has a better overall burger, though perhaps the "flipped" burgers @ Flip (made with nontraditional burger ingredients) are where the place shines. The milkshakes were incredibly fun and inventive (also on the menu: Turtle shake, Key Lime Pie shake) but thinner than I like my milkshakes, while the nutella one was too rich to finish (a pro and a con).
However, it was a great place to take out-of-towners and townies who hadn't been yet (that includes us) but for a better burger and more relaxed atmosphere, I'll head to Farm Burger.
