In regards to a recent review that claims this restaurant is expensive, I disagree. On the one hand, if you go by the logic that Oiistar serves ramen, which is known for being the cheap meal of choice for college students nationwide, then yes, it is much more expensive than those ramen noodle packets you can pick up at the store. But this restaurant doesn't serve your typical ramen noodle packet (thank goodness because that would be a stupid concept); Oiistar serves delicious ramen noodles made in-house and cooked in a savory broth with meat, vegetables, egg, spices, etc.
Also, yes, it would be expensive if you bought FOUR bowls of soup for only TWO people, as the previous reviewer says he did, but that is rather ridiculous. Each bowl of ramen is HUGE! On the two occasions that I've gone to Oiistar, I've been very hungry but haven't been able to finish my bowl. My boyfriend is a big guy, and he can just barely finish the bowl. It's a giant portion, so there's no need to order more than one bowl of ramen per person. For two people, you can go here and get one or two drinks, an order of buns, and two orders of soup for around $50, which I'd say is a good value for a trendy Chicago restaurant with high-quality food.
Speaking of the food at Oiistar, the ramen is excellent. After my first visit, I started craving the ramen and wanting to go back for more (which I ended up doing last night)! I've tried both the Tikkamen and the Chadolmen "modern" ramen. The Tikkamen included chicken, masala, and bean sprouts and was reminiscent of Indian cuisine. The Chadolmen was perfectly spicy (i.e., it had a definite "kick" but wasn't so spicy that I couldn't handle it). The Chadolmen contained a tasty mix of the following: beef brisket, kimchee, spicy miso, garlic, bean sprouts, cilantro, and egg. And of course all of the soups include generous portions of the house-made ramen noodles. Both soups had an addictive quality; once you start to get full, you still don't want to stop eating it! Oh, and when the soup comes out, all of the ingredients are partitioned to their own side of the bowl. I recommend mixing them all together!
As for the buns, I've tried three of them and think they are good but not great. That might just be because I've eaten amazing buns in New York and not much seems to compare. Each time I've gone to Oiistar, I've been so excited to try the buns, but they've failed to live up to my expectations. For one, the buns are tricky to eat. I feel like you should be able to pick them up and eat them like a taco, but instead, I always end up eating them with a knife and fork, which seems strange. Also, I think that when you order these buns, it would be nice if they'd give you more than one per order. They're tricky to share. I will say, though, that if you want to try the buns, the best one I've tasted so far was the pork belly bun.
In regards to drinks, they offer house-made sangria. My friend ordered it and let me take a sip. It comes in a cool mason jar glass and was quite good. I plan to order it for myself next time I go!
As for ambiance, the restaurant has a "hip" feel and is fairly small. Both times I've gone, I've been seated at the bar area where you can watch the chefs cooking your ramen and buns. My main complaint as far as the seating is that the seats at the bar are tall wooden chairs that aren't very comfortable.
The service is fine. Nothing to really rave about, though. One plus is that on both occasions that I've gone to Oiistar, the chef, Sunny Yim, has been there. I like that. Sometimes, you go to a restaurant, and the head chef isn't even there. Last time we went, he thanked us for visiting before we left. I thought that was a nice gesture, and it's always cool to meet the head chef! read more
