Nak Won Garden (NWG) is pretty good. This was my third or fourth time there and it's been consistently good. The latest trip was for lunch, which is usually when I go and there's maybe two other occupied tables around that time. I've never had to wait to be seated so the fact that they don't do reservations isn't an issue for me. It's a good time to go for a casual lunch because you don't feel like you're occupying other people's space given that their tables are fairly close together.
Each time I've gone they've had Kpop playing (Super Junior, etc.) and it's a very casual environment. I've only been there during lunch hours so there's usually only one person greeting and taking orders. They usually seat you closer to the door/windows which is fine. The waitress was very sweet and they're pretty good about checking in on you without seeming overbearing but also very present if you need anything. It's the perfect combination.
The food is really good. I usually bring new people who have never had korean food before so they generally get the bibimbap. I like it as well, although I've tried a few other things there. Most recently, I got the Dolsot (hot stone) Bibimbap with chicken and my friend had the marinated beef. Both were good but it's pretty mild without their spicy sauce which I assume is some kind of gochujang. They both had the traditional fried egg served on top, which I love runny. It's $14.99 which honestly isn't bad. They do have bibimbap for less that is not served in the hot stone. This last time they served less side dishes but in larger portions which was totally fine. The kimchi was great. The Mochi ice cream was divine. Everything was good. I've never had their BBQ or their Bulgogi but that's next on my list. I already have plans to go again after friends saw some of my pictures. Also, order the dumplings--it's a must.
I will say that they try to sell you on appetizers which is fine because they're worth it. My friend and I were going to split mochi ice cream (they come in a set of 2) but she just brought out 4-- we didn't complain. We both walked out spending $25-30.
