Penthai — Mt Prospect thai that sets the standard. Straight from the source, no adjustments, and affordable. "If you’re sensitive to spicy food, the medium spicy tier may be too spicy" — Darian Duchan

“This is one of the most delicious Thai food restaurants I visited and I had visited many”
Super small portions AND it gave me AWFUL food poisoning.
View photo at your own risk. We ordered 2 dinners and there was a bug/roach cooked into the food.
I had high hopes since this restaurant has so many good reviews.

Amazing Thai restaurant! The food is bursting with flavors—Pad Kee Moa,pad thai, lots of great noodle and rice curry dishes. The green curry are must-tries. Service is friendly and attentive, creating a warm atmosphere. Highly recommend for a delicious and satisfying dining experience!

“It's been so long since I've had Thai food.”
It's been so long since I've had Thai food. Thai food isn't something I crave often, but I love it every time I have it. Pen Thai delivers big on flavor and calm atmosphere. I tried their Papaya Salad, Pad Thai w/ chicken, Red curry all at spice level 3, Pad Kee-Mao w/ chicken (spice level 2 & 3 & 4), and green curry w/ tofu (spice level 2). I love spicy food and Thai spice REALLY brings the heat! It's so addictive and delicious, but honestly, I think I'll stick with level 2 from now on to give my tummy grace. Service is always quick and everything is always so tasty. The value of all the items is also affordable compared to other Thai places I've been to. Thankful for this small gem of a spot so close to home! Definitely felt the kick the dining area had a calm vibe, and the service was excellent. A great spot for delicious Thai food and a relaxing meal!

Super cozy place and the food had amazing flavor. The service was great and the vibe inside was chill. If you’re sensitive to spicy food, the medium spicy tier may be too spicy

“This is the best Thai that we have found in the Chicago suburbs and are absolutely in love.”
This is the best Thai that we have found in the Chicago suburbs and are absolutely in love! We were just in Thailand and missed great Thai food and this sure did it! The owners served us and are super sweet and charming. And the price was really low for how great it was. DEFINITELY recommended. My wife looks white with her blond hair and galaxy green blue eyes but she is Asian on the inside. She lives on Asia for years and she highly approves!

Let me just say that if you like curry and spicy, then you are not going to be disappointed. I had 4 out of 5 heat, and it was yummy. I tried their curry puffs, which were a little dry, but they were pretty good, too! Great Thai spot!

“We came here once before.”
We came here once before. This visit was during lunch. We didn’t know they had a lunch special starting at $9.95 depending on the protein you select. This is one of the most delicious Thai food restaurants I visited and I had visited many. We ordered the pekimao with beef and the of Thai with chicken. Everything was done very nicely with flavor and not over cooked. The drunken noodle was a little spicy but within my tolerance. They also add small appetizers such as egg rolls and fried tofu which makes the meal even more worth paying. Everything was great. I wish they would update their floors but other than that it was great!
