i've been really enjoying the shaved ice at boba time on the corner of national and sepulveda. they have 5 choices- mixed fruit, mixed fruit deluxe, mango, green tea, and coffee. the owner is really friendly and is more than willing to accommodate topping substitutions. i'm not sure what exactly defines korean shaved ice, but they are very generous with the fresh fruit, red bean, mochi, ice cream (or pinkberry-esque yogurt), boba, etc.
prices range from $5-6 for shaved ice and the place has free wifi. it's basically your standard asian drink/froyo place but i think i'll be sticking to the shaved ice. i really like the level of control i have in what goes into it...most places will be stingy with ingredients or will not allow substitutions.
