“I got the oiimen ramen, and it was creamy, gentle umami, and delicious.”

I got the oiimen ramen, and it was creamy, gentle umami, and delicious. It wasn’t spicy at all, so I might try the umami ramen next time since it’s noted as “level 2” spicy in the menu. The pork belly bun was delicious! The meat melts in your mouth 🤤 I got the poached pear, and it was a lovely way to end a hearty meal. Fluffy cream, not too sweet fruits, and an overall light dessert to cleanse your palate. Satisfied with my meal! Staff is super attentive and be ready to be a little scrunched in the small restaurant.

“This might be my new favorite ramen spot.”

This might be my new favorite ramen spot! As someone loyal to Gyuro Ramen for their rich gyukotsu broth, I wasn't expecting to be blown away, but Oiistar completely exceeded expectations. Umami Ramen - Absolutely incredible. The broth has this perfect umami depth that rivals the best tonkotsu I've had. Spice level 2 was spot-on, flavorful heat without overwhelming the complex miso base. The Berkshire pork belly literally melts in your mouth, and they're generous with both meat and broth portions. This is easily two meals worth of food and completely satisfying. Bao Buns: Berkshire Pork Belly Bun - This set the bar high and delivered. The pork belly is rich and flavorful (essentially the same as what’s in the ramen), with great contrast from the cucumber and daikon sprout. The sweet sake soy reduction ties it all together beautifully. Must try. Tempura Shrimp Bun - Good but not memorable. The shrimp was well-battered but got lost under too much pickled fennel slaw. The Thai sweet chili mayo was nice, but wouldn't order again. Service was excellent - staff helped me pick my ramen and gave great recommendations. The atmosphere is perfect for a casual ramen experience, and thoughtful touches like having a proper coat rack show they care about the details. Highly recommend!

“This restaurant is PHENOMENAL.”

This restaurant is PHENOMENAL! Food came out in less than 10 minute intervals, and we had a VIP view of the kitchen at our seats. The quality of food was next level - each item was meticulously plated and each bite was better than the previous. Highly recommend, it is the best restaurant in Wicker Park.

“Pretty solid spot for some ramen (4.5/5 stars).”

Pretty solid spot for some ramen (4.5/5 stars)! My friend and I visited here on a Tuesday afternoon so thankfully there was a good amount of space for street parking. Right when we walked in, we were greeted by a very welcoming/friendly server who took us to our seat. I enjoyed how open and aired out the restaurant felt. The big windows also allowed so much natural lighting to come in which felt nice during lunch time. This is what my friend and I ordered: Tonkatsu Buns Umami (Spicy Level 2) Paitan Shio Fried Garlic Chicken Sambal Both ramens had a savory, rich broth which was very satisfying. The char shiu (pork belly) was an absolute star- so tender and flavorful (honestly the best I’ve had in a while). The portions are also pretty large too so I had to take my leftovers to go. The Tonkatsu Buns were good but nothing really special in my opinion. As for the fried garlic chicken, the flavor was spot on but the texture was okay- I wish it wasa tad bit crispier since the sauce made the exterior a little soft. Overall, my friend and I had a pleasant experience at Oiistar and we can’t wait to come back and try more items from the menu!

Very Yummy! I had the Pozolomen and i personally didn't like it much, it had diced tomatoes and that threw me off but my brother had the musselmen (mussel ramen) and that was delicious! I want to go back and try other bowls.

“I had an excellent experience at this ramen house.”

I had an excellent experience at this ramen house! Based on my server’s enthusiastic recommendation, I ordered the Paitan Shio Ramen with Fukuoka Garlic, and it absolutely lived up to the hype. The broth was rich and flavorful, the meat was tender and delicious, and the tamago was perfectly cooked—not overdone, just right. I’m already looking forward to my next visit to try more dishes!

“I ordered Mashed bun and Paitan Shio Wha-da-hac spicy ramen, and the portion was huge.”

I ordered Mashed bun and Paitan Shio Wha-da-hac spicy ramen, and the portion was huge. I could only finish the half of it. Also, the ramen broth was fantastic. They give you the wha-da-hac on the side, so you can experience the broth without it and also control the spicy level. Great service, too. Highly recommend!

“If you're into ramen, this is a must.”

If you're into ramen, this is a must. It’s a bit far from downtown, but absolutely worth the trip, the area is trendy, full of interesting shops and local businesses. We had the oiimen and chadolmen ramen, both were excellent. Portions are generous, perfect for sharing. You can choose from three types of noodles; I went with the gluten-free option and it was great. The beef brisket was tender, flavorful, and melted in the mouth. The broth was served at the perfect temperature. The Oiimen is labeled as spicy level 1, but it's very manageable, just a hint of spice with great flavor. I also had a glass of Mionetto Prosecco, which paired wonderfully with the meal, highly recommend it. Service was really great, the waiter was kind, attentive, and happy to make suggestions, the place was full of locals, which I always take as a great sign of quality in food, not just a touristic spot. A great option for ramen for sure.

“The ramen was great.”

The ramen was great! The broth has a great flavor that’s very deep and rich. The pork belly has a great char to it as well. Our server was awesome and friendly. The portions are also big enough that we made three meals each out of our bowls. Definitely worth going to!

“Stopped by here with my boyfriend as a random place to eat and we enjoyed it so much .”

Stopped by here with my boyfriend as a random place to eat and we enjoyed it so much ! The buns where amazing we had the shrimp and the pork belly and they where to DIE for ! We also ordered a mashed one but we didn’t enjoy it as much as the other two. Although still pretty tasty. We also had the spicy garlic ramen and it was amazing !!!! Definitely a place to try and it was very reasonably priced ! If you’re ever. In town check it out !

“About a month ago, I had lunch at Oiister.”

About a month ago, I had lunch at Oiister. Totally forgot to leave a review. But today, while going through my photos, I saw the ramen pictures I took, and it reminded me of how delicious it was. The ramen was amazing. Perfectly grilled piece of pork, rich broth, plenty of ingredients. What could be better? The atmosphere is pretty chill too. You really don’t want to leave. As for the service, no complaints here either. The staff is super polite, not pushy at all, didn’t come by a thousand times to ask how the food was or if I needed anything else. Overall, I’m super happy!

“Ramen is delicious.”

Ramen is delicious! They have rice noodles for gluten free. They also have Sapporo on tap, Two Brothers gluten free beer and few other gluten free options as well. Ramen are huge. It gets very busy on weekend nights but service is fast. We ate sitting at the bar and it was fun.
