As far as I am concerned, they are the same. It's just that samgyupsal has a lot of side dishes; steamed eggs, meatballs, squid balls, rice, noodles, cheese, bean sprouts, small potatoes, miso soup (although I think Koreans don't call it miso soup, but I'm pretty sure it's miso soup), and many others but it won't be complete without Kimchi. When there's Kimchi, then it's Korean Barbecue. If it has just the meat and the grill, and rice, that's Yakiniku.
But what makes Samgyup Story unique is it's service. The servers are quick to refill your empty plates of meat strips without you having to call their attention. Here it's quite the opposite, you have to call their attention just for them to stop the refill lest you want the meat wasted because you're so full and can't eat another bite. For the most part, you cook your own food on the grill at the center of the table. But there are times when you're just too busy cooking and not doing any eating anymore, the servers will actually do the cooking for you while you eat. And in some cases, even the owner will do it for you. They also have traditional Korean outfits that you could wear so you could take a picture in from of their backdrop that seems like a scene from one of those Korean period dramas. And if your pitcher of water seems to be no longer cold (or maybe because it's summer) they will change it for you even if it's still half full.
For the grill itself, they don't use burning hot charcoal. They use a flame from a stove which produces little to no smoke. This is good considering the restaurant is not air conditioned, no overhead exhausts over the grills, and uses only electric fans.
Now I'm sure you want to know about the price. Well. For a place that serves unlimited refills on almost everything, it is priced low; Php 299 on their cheapest set.
