We order take out quite a bit and the last few times the food has been cold to lukewarm. It seems to be on nights when you are not busy and they get to it right away. Then it sits on the counter while wait for the twenty to thirty minutes you give as wait time. I am very disappointed.

We had such a great experience at Cosmos thanks to our amazing waitress, Rosie. She was so friendly, thoughtful, and truly went above and beyond. As a young mom herself, she completely understood what it’s like dining out with a toddler, she just got it. She brought out our son’s food early, brought to-go boxes before we even asked (because with a toddler, you’re always on borrowed time!), and made us feel so comfortable and cared for. It’s rare to have someone anticipate your needs so naturally. We left saying, “That’s how customer service should always be.” Rosie was absolutely lovely and turned what could’ve been a stressful dinner into such an enjoyable one. We will be coming back more frequently.

I enjoyed a delicious Italian dinner at Cosmo's Italian Kitchen in RSM. The sauce for the lobster ravioli was creamy, with a balanced mix
of spices, and the bread was soft and fresh. The server Henry was very attentive and professional. The ambiance is also quaint and cozy.

I would highly recommend dinner at Cosmo'. The ocation is not too far from the 5at the corner of Oso and Antonio,

We have used cosmos for catering for 2 parties. The first party when when they were closed so the planning was different then and we tried to give the benefit of the doubt. The food is a crowd pleaser. Delicious. But when your oder catering and are PROMISED some very necessary items in order to serve them at your function and the restaurant falls through. Kind of a bummer. Party 1) they just straight up didnt give us the promised chafing dishes and sternos. We moved on and made the best of it. Ordered again for another function that we were hosting. After them not confirming the day before like they promised I scrambled to confirm. My husband went to pick up. Food was ready. But the promised chafing dishes were not ready and in storage. They also did not have ANY sternos on hand again, as promised. So my husband had to scramble to find a store with sternos as directed by the manager. This was discussed prior and promised both times by the person who took the order. Unfortunately my husband showed up very late into the party because he had to find the sternos. Overall disappointed in the customer service and organization in the catering. While we love to visit for a meal in restaurant we will be finding alternative Italian catering options due to repetitive disappointment

One of the best Italian spots in the city. Cindy's special is the best thing and the meatballs are great.

Remember when this place served authentic NY-style food? When they first opened in aliso What a letdown tonight. $31 cioppino for nothing, couple chopped up pieces fish and mussels a few shrimp and some water not even a side! It’s turned into a money grab. Nothing like when it first opened. It's sick what there giving for 31 dollars 😂 save your money! I left completely pissed for spending my money there.. I should have taken picture for all to see

I cant say enough about their catering service! They went above and beyond on the call of duty. Q and Henry were very helpful and answered all my questions. And the chef took really good care of us.

Where do I start. The atmosphere was great ? Very Italian and the music was Sinatra at his best! Huge basket of bread! (on the house) olive oil and balsamic for dipping! Of course, I got some garlic to put in the dip again, with no charge! BTW, the prices were very inexpensive, like the fried mozzarella sticks were so good to start! I ordered my fav Eggplant Parm! My buddy got the Diavalo sauce with pasta. I heard him say it was the best meal he ever had, and he used to live in Chicago!!! The waiter was always around to please our every needs. We thoroughly enjoyed ourselves and will go back soon! Thanks, Cosmos!
