The OP Cafe is very quaint and cute, the food is pretty good, the feeling is quite homey... but it doesn't quite make up for the slow kitchen. Apparently it's a common problem here-- they warn you-- but given how many other cafes are around, it's hard to justify making a special effort to come here.
Dinner at Jjukku Jjukku that night. Pretty average as far as kbbq place goes, although the extended smoke hoods are a nice touch. Menu seems to be a tad more expensive, but the garlic beef is excellent (if slow to cook... is that a theme today?), and beef tongue, while stingy in portion, is pretty tasty too!
