Bobby's Burgers and Shakes, Hongdae

Bobby's Burgers and Shakes (locations in Hongdae and Apgujeong) has a retro, 50s feel to it, with shiny whites and oranges dominating the interior, and smooth graceful seats. The burgers are about 8,000-10,000 won; the shakes are expensive, of course, running about 6,000 or 7,ooo won, and the fries, sides, cokes, etc. are all about what you'd expect (think roughly Kraze prices).
The quality is good, though. These are American-style burgers; and they're delicious. I think they're a bit below Burger B (down the street from the Hongdae location of Bobby's Burgers), but they're juicy and meaty, and they definitely crack the top ten. (And Meg really liked the fries, btw. They're the kind that taste like they have mashed potatotes inside, if you're into that. Personally, I prefer a less mashed texture to my fries, though.)

Directions:
Hongdae: Go out Hongik University Station Exit 5 and walk straight. Turn left at the first intersection (but not at the street that is right outside Exit 5). After you turn left, walk up the street for a while; eventually you'll come to the end of the street at a three-way intersection (which is where Hongik University itself is). Turn right and Bobby's Burgers is right there.
