Izawa (이자와) is another gyukatsu (규카츠) restaurant that is nearby Atto Gyukatsu that I've shared a couple of posts ago. This place, also in a basement, has a slightly bigger seating area compared to the other place. Gyukatsu (규카츠) is what I always order, and sometimes their Steak Don (스테이시동) if I come with a friend and we want to mix it up a bit and order to share. Their set menu comes with salad, side dishes, miso soup and rice and if you ordered their 2 persons set menu, it also comes with a choice of drink. I personally come here more often cos I like their gyukatsu slightly better. I think the beef is more tender and the stone plate grill that they use makes it easier to grill the meat (plus they change the grill plate for you quite a bit so your meat doesn't stick to the grill).
I've came here a couple of times and the place is pretty packed during lunch and dinner hours (you might have to wait in line for a bit, especially if you come in big groups more than 4 people). But Koreans usually eat pretty fast, so the wait time is not that long. Or you can always come before or after the lunch/dinner rush, like I do all the time ;)
