I must have been unsensibly hangry when I reviewed Bachi last time. Yes the service is hit or miss, but the burgers and fries.... amazing.
I've tried a few of the burgers, but I never stray too far from the Myagi-San. We have an off-and-on relationship, and we like it. The ox tail fries are delicious, but warning for those sensitive to spice -- ask for a few less jalapenos!
The wait can be anywhere from 5 minutes to 45 minutes, but the burgers are so juicy and delicious, I think it's worth it. Maybe just don't come with me when I'm hungry.
