To my delight, Fusebox is finally offering Saturday lunch hours in addition to their current W-F lunch schedule.
The Korean Fried Chicken wings are very different from the batter and sauce heavy places in Oakland. The skin here is thin, crispy, and brittle. The wings are fried once, not twice, and apparently the chef applies the sauce on with a paint brush to keep the skin from going limp. The chicken is very white, likely brined or marinated, and the meat juicy and flavorful. The quality of the meat is high, and I'd rank it on par with what you can get at Wings Wings. Not sure what they use in their sauce, but at the risk of saying something very ignorant, it resembles more what I've had at Japanese than Korean restaurants.
The Busan sandwich was pretty good, and well matched to its bread. It could use some more veggies. It consists of pork belly savoy cabbage & pickled white zucchini. It was served with house a small pickled carrot and watermelon radish.
On their specials today, for a dollar each, they had grilled eggplant in a butter miso glaze and grilled king oyster mushroom in a butter miso glaze. The glaze paired better with the mushroom.
I really like that they have, mostly on the daily specials menu, lots of $1 or $1.50 grilled small bites. The portion sizes are of course tiny for that price, but it gives you an opportunity to eat a wide variety of items without breaking the bank, something you certainly can't get at any Izakaya place in the Bay Area.
The neighborhood is mostly warehouse space, so I'd be curious to see if they ever have dinner there.
