"Nice atmosphere, clean interior, fast service, and food is top notch. Can't go wrong with the wings, but make sure to get the IDK fries. You will thank me . Desserts are on another level, and if you are a lover of wings they won't disappoint. All the teas and lemonades are made in house. Can't say enough about this place. Glad someone took over this vacant location and turned it around."

"Refreshingly full of flavor! I finally stopped in after driving by the last few weeks and was glad I did. I ordered the Whatever Falafel, Gyro… I guess? Sandwich, a peach tea, and baklava from the dessert counter. The food was delicious, very flavorful but didn’t leave me feeling like I indulged too much! The gyro meat was tender, moist, and packed with flavor! I really enjoyed the subtlety of the falafel, the flavor was fresh and natural tasting (however nicely fried hehe). The teas and lemonades are also very good without being so disgustingly saccharin sweet, like I can genuinely enjoy it on a hot day without feeling like I’m dehydrating myself further or get that nasty syrup spit feeling. They also appear to be cutely bottled in house with a clear body and can lid, I didn’t ask but I saw cups without lids so I believe they do it themselves. Lastly, while not listed on the menu they do have a dessert bar at the counter, I went for the baklava but I also saw what might have looked like a Dubai chocolate cup! Overall very pleased and so happy to leave close by! Photos of food are in my own home, not the restaurant as I got my order to go. Their wall inside says Halal as well for the communities that look for it as well as a small children’s menu “Little I Don’t Knows”."

"Tried out this new place in town and was pleasantly surprised. They had a variety of foods on the menu from Burger and wings to gyros and falafel. The kids menu is also extensive. The flavored lemonade are especially good. You walk in and order like fast food and take a seat and your food is then prepared."

"I WENT HERE ONCE, FIRST TIME AND MY BRAIN MELTED HAVING THE FOOD WITH MY FRIEND. We got the Chicken Shawarma, two flavors of wings, a salad, Lemonade, and then I ordered a Gyro for my mother and all of it is so good. Cannot recommend this place enough! They also have Freez and Jarritos, but I'd recommend their lemonades more so"

"Tonight was my first time going, I had wings and IDK fries. Haven't had any fries like those around! Everything was so good, and you can tell they care about the taste and quality of their food. It's detail like that that makes all the difference! The flavored lemonades are good too, I had the prickly pear flavor. Really excited to have somewhere good nearby to try a lot of different things, I'm looking forward to trying some fish. My son got a burger which also looked good, I'll be back for sure! Keep up the good work and keep up the quality standards! I highly recommend"

"Our first time in the restaurant. It can be a bit pricey depending on what you order, but they are so nice. And the food is SO good! Drinks are in a special container which took us by surprise and very clever! The only issue I had was that we ordered only two rice bowls and 3 were wrung up. Oops! That's ok. Leftovers haha! We will absolutely be back! Thanks guys!"
