I'd never been to Gen in SoCal (too many options, not enough time) but I've been multiple times now that they're in the valley. I'm always surprised at how quick and prompt the service is here. Most other Korean BBQ places will start to ignore you after the first few plates, forget to bring plates you ordered, etc., but the staff at Gen always seems to come around at the right time asking what you want for your next order and changing your grill constantly. The ventilation is also a lot better than most other places which is good for how big the place is. Quality of the meat has always been good. The portions are on the smaller side but I actually prefer that because I don't end up ordering a final plate that has way too much for me to finish - plus, as mentioned before, the staff is always coming around, so I'm never left with much downtime between plates.
