Shin Sen Gumi
Late night all you can eat (AYCE) shabu shabu at Shin Sen Gumi Horumon in Gardena!
Serious nom-nom-nom... I don't know how many servings of angus beef we went through, but it was a lot. Our randomly planned little group also ballooned into a big one. Turns out the tables there fit up to 8 people. We managed to squeeze in ten. Somehow.
The real secret now is seeing if we can go again, or if we've been permanently blacklisted from the place. :-p
