I commented this but I'll throw it on the board since I think it merits 5 stars now, unless you guys are holding out on the 5th star due to the fact that they're closed nights/weekends. I hate that.
Muracci's now offers Cheese, Potato, and Vegetable toppings for their curry. I'm eating the Katsu Curry with the Cheese & Potato. They actually also hooked me up with some perfectly cooked Carrots/Broccoli. The cheese was mixed into the sauce and it just adds an out-of-this world creaminess that's to die for. They were already my favorite, but now they're really near the top of the list for best curry in the country! Anyone visiting San Francisco on a weekday really needs to do themselves a favor and swing by here (11:00AM-12:00PM and 2:00PM-Closing is the best to avoid the rush)
