I have a soft spot for Ho Su as I lived around the corner for almost 8 years. Its a perfect cheap and cheerful lunch or take out spot. Its fast, fresh and consistent.
My favourites are the vegetable gyoza, the vegetable tempura and vegetable rolls but they also do a very nice bento box for lunch that I think I posted a picture of when I was there last. I used to eat the fish and found it quite fresh here but don't eat is as much anymore. I thoroughly enjoy the vegetarian options here.
When you dine in you automatically get tea (if you want it of course!) and a kimchi plate and some edamame. Nice touch even though I don't fancy the kimchi. It's fast, friendly and fresh - and the take out counter is just as friendly and effecient.
High marks for Ho Su in my old hood :-) Dine-in, take-out or delivery.
