Have tried many Korean bbq joints in Vegas. This one is good but the whole family agreed it doesn't better our favorites. They all do a decent job so it depends on your point of view, but what we didn't like about Gen was the following:
1. Banchan dishes are small and we had to order some of them repeatedly and oftentimes the waiters would just forget to bring them.
2. Their bulgogi marinade is unlike any I've tried. Seems to lack the traditional sweetness, soy and other requisite ingredients. Not sure how you can mess up this quintessential Korean dish.
3. Very loud music, too much party atmosphere. It's not the strip.
4. Full price for any kid over 7 years old, based on height. Not even my 9 year old was even close to eating $22 worth of bbq.
Thumbs up for the nice green tea salt, a nice surprise that you can't find too easily elsewhere. Banchan recipes were tasty and fresh. Garlic calamari was a hit. So was the head-on shrimp.
