Just had lunch there as a family of 5 and all of our meals were delicious! The bread was seasoned great, we had tasty calamari, I had a daily special – truffle mushroom risotto with scallops and goat cheese…it was to die for! My husband had the lobster avocado grilled cheese and thought it was delicious. My daughter had the chipotle BBQ pulled pork and loved it, my older son enjoyed his burger and my younger his chicken tenders. They dont have a kids menu but can make tender or cheese pizza (not on the menu). The service was very friendly and our waitress was kind and tentative, especially with our drink refills. We stopped here on a whim and boy am I glad we did!

Dined here for the first time in Feb 2026 and was one of the best dining experiences Ive had in a long time! Every item we ordered was delicious. I’m still thinking about the potato skin nacho appetizer a week later.

Unbelievable. There’s a few times in life where you know “oh that’s the best fill in the blank I’ve had” and you remember it. Somehow Olios mashed potatoes knocked me into a different dimension. Everything was great, my steak, my wife’s meal, our appetizer, our desert, their bread, the coffee, all great. Service was great. But the mashed potatoes and gravy which doesn’t even make sense made me stop in my tracks and just enjoy it. The prices were fine for the high quality meal as well. Just as good as anything at the casinos, or other higher end restaurants in the area but half the price.

We went there for a business lunch, 10 people. We had a reservation, but it shouldn’t be a problem finding a table. Most of them were empty when we got went. There is parking lot outside so parking won’t be an issue. Cozy place with large chairs and sofas, very comfortable. The service was flawless, very kind waitress and always there to serve us with no delays. We didn’t wait long for the food , all the dishes came at the same time. There was a variety of choices from burgers, pizza and pasta. The portions were generous especially for the pasta.

A friend recommended me this restaurant. I decided to take my mom out to dinner for Mother’s Day. My experience was 10/10. Michelle was our server and she was AMAZING! Michelle was super friendly & accommodating! I got the fried goat cheese balls as an app, gnocchi for my entree and the chocolate lava cake for dessert! I can’t wait to go back again soon!

Nice restaurant with prompt service and a calm ambiance. Most of the food we ordered was very well prepared, except for the Clam Chowder which was in dire need of salt. On the other hand, I would highly recommend both the Lobster Avocado Grilled Cheese and the Chicken and Goat Cheese Sandwich, which each had great texture and were bursting with deep flavor.

Excellent meal as always from Olio. Great menu options. Specials are always fresh and intriguing. Had the halibut special with French potato salad and yellow pepper sauce. Fish was well seasoned and flavorful. Only complaint would be that it may have been just a touch overcooked and thus a bit dry….this is preferable to underdone though….potato salad was refreshing on a hot day and the yellow pepper sauce was a nice compliment to both… My wife had the salad pizza which she said was excellent and enough for lunch the next day. For dessert we had the banana and chocolate ravioli with malted milk ball icecream….this was outstanding and more than enough to share….could easily have served 4 with it. Our waitress Stella and the entire wait team was attentive and courteous. We thank them for their work and efforts. Would definitely recommend for a nice evening out with friends or romantic dinner date.

My fiancee and I come here all the time for our date nights. What I should say is we USED to come here. We will no longer be. I had planned a small surprise bday dinner for him and his sister and her husband. I had told them ahead of time. His sister and her husband got there first and they sat them. We came a few minutes later. They didn’t sit us with them. So the surprise was completely ruined. Then I ordered a $50 filet mignon. I ordered it medium rare. It came in WELL done and the rest of the food (asparagus and mashed potatoes) were ice cold. I asked the waitress to take it back and they cooked me a new piece. This second piece came out butterflied (which you never do with filet) and it was completely RAW. I, again, told the waitress it wasn’t cooked right and she took it back and they just cooked that same piece. It came back rubbery and disgusting. I couldn’t even eat it. It literally went right into the garbage. So how did they fix the fact that they ruined my fiancées dinner and my $50 steak? They gave us a TEN dollar gift card. We just threw it right away. What a joke. The steak should’ve been comped. I will say, the waitress was very nice and she tried to do everything she could. It wasn’t her fault. It was the owner, the manager and the chef’s fault.
