I've been to Midori twice recently. Located at 301 Percival Road near its intersection with Forest Dr., Midori is housed in a small strip center with two other shops. One of which is a small international grocery store.
On my first visit, I ordered my standard toeji bulgogi (spicy pork). The meat was thinly sliced, tender, appropriately hot and not overly sweet. Very good. My companion ordered Kalbi and she said it was better than Obok's but not as good as New Seoul's (RIP). Apparently, it tasted good but was not quite rare enough and wasn't charred.
On our second visit, we ordered the seafood pancake for starters, only we asked they hold the seafood and make it a vegetable pancake. We ran into a bit of a language barrier at this point but it was worked out when another employee with better english skills came over. Moral: they do have someone there that can understand what you're saying. The pancake was easily enough for four as an app and it was delicious. Next, we split toeji jeon gol, a spicy pork and tofu stew. We let the broth reduce and the concentrated flavors were rich and satisfying. We were glad to find someone serving this dish. Our only complaint was the little pieces of pork they used were overly fatty.
We were also served about a dozen side dishes that were all good.
Don't be put off by the location or the neon beer signs in the window. The folks inside are friendly. However, don't let the waitress dissuade you from ordering what you want as she tried to do to one of our group on our first visit. To me, Midori is in the vein of a true chowhound place. The timid will never venture there but the more adventurous will be rewarded.
