Cosmo’s restaurant is fantastic. We enjoyed their delicious Soup and Pizza, both of which were excellent. The staff is very friendly, and the atmosphere is wonderful. We traveled from Toronto and had a truly enjoyable experience. I highly recommend it.

The best chicken Caesar I have ever had! So much meat, and I must say it was packaged very well with the meat and cheese seperated from the salad. God job!

Great work ethics and etiquette, the food was really wonderful. Homecooked comfort food vibes ..family atmosphere! My son loved their pizza.... Highly recommend, definitely will go back.

I'm a real critic when I comes to restaurant food. And this place is at the top. We came for the first time for lunch. Food was eccellent, affordable, very lage portions everyone brought left overs home. We will definitely come back for super in the future to try it.

The local neighborhood resturant for my entire life! Always loved the pizza and atmosphere!

I love Cosmos for so many reasons! The buns are UNREAL... honestly that’s reason enough for me to go there BUT there’s more! Their family meals are awesome huge try of pasta, family salad and 4 of their famous buns! Staff have been there for decades and are lovely! Pricing is a deal!

We so enjoyed our meal. Ordered a chicken parmigiana it came with a huge salad with house made dressing, and humungous homemade roll. The pasta was cooked the way we asked perfectly, perfect amount of tasty sauce. They put Parm and chilli flakes shakers on the table. We also ordered a super pizza it had lots of toppings and canned mushrooms (I love canned mushrooms on pizza). Our server was great and all our answered questions. Worth the drive from London. We can't wait to come back. I'm adding an edit the next day. We ordered the lasagna meal to go. OMG the best lasagna we have ever had. We got a huge pan, 4 of there homemade rolls, a large salad with the house dressing, they also added a bag with butters little bags of chili flakes and a good size bag of parm. I cut the lasagna in half and froze 1 part and 2 of the rolls. We had more the enough to feed 4 adults and 1/3 of the salad left. We ran out of dressing tho. It was easy to heat up and we have another meal of the lasagna and rolls. Also some salad for tomorrow that I'll just add some more stuff and dressing. Great value for sure but even better was it was so good everyone loved it. Just an update we froze 1/2 the lasagna and 2 rolls. I it heated up covered for about 45 mins and uncovered for about 25 mins. It was a bit watery when I took the lid off but after the 25 mins it was perfect. I heated the rolls up and cut in 1/2 buttered them and they were so good. OMG it was all just as good as the 1st night. Just wow....
