What a time warp this place is. Classic Greek-run diner with decor to whip you right into 1980. Pastels, linoleum, and those ever-so oddly placed statues. Give this place another 5 years and maybe just a table top reno and this place will be the next retro hub coming totally full circle. [please get those table top music machines that you can flip through pages of songs and play for a quarter!! Lean all the way into it!!! Extensive menu- of course. But went with a Turkey and cranberry sandwich (comes with chips) Slippery dumpling order with chicken And a chocolate milkshake (hold the whipped) Service was pleasant and attentive. Food came out quickly. And for a $24 dinner, I really can't say much. Plenty of parking. Big ol neon sign outside so you can't miss it. For an off the beat, local diner in sort of the middle of nowhere, did the job. Over heard a few other customers talking about having ate there earlier for breakfast now coming back the same day for dinner so I'm sure the locals love it. Seems the kind of place where they get a lot of regulars. read more

Cosmos is one of my old school go to spots. They do the basics, and don't mess anything up. Place is clean, and the food is prepared well. Service is always on point and friendly. read more

It had been a while since I've been to Cosmos and was looking forward to reunion, but nothing was as advertised. Ordered one of the specials, the cream chip beef which was listed as over toast with home fries. When the plate arrived I discovered that the bread was not toasted at all. It was just two slices of bread cut diagonally stacked diagonally on the plane with a chip beef on top. The cream was extremely thick the whole bite of bread and cream was just a glob of stuff in your mouth tasted like glue. The home fries were in fact hash browns and were undercooked and mushy. Not my definition of home fries. Then I had ordered scrambled eggs and made it very clear I was particular as to them being light and runny . Apparently the cook doesn't understand how to make scrambled eggs as they were cooked solid on the bottom and kind of wet on the top so they never been actually scrambled or flipped. Interesting that the water glasses are in fact metal, but that's fine. The waitress was adequate and polite. Overall kind of disappointing that a diner can't get a diner staple like chip beef correct. read more

I ordered the French dip and it was absolutely horrible! The meat had no flavor whatsoever. I think they boiled the meat. I am never coming back to this rip off joint. read more

Ordered from DoorDash. Ordered a hot turkey sandwich and mashed potatoes with the gravy on the side. Order arrived with beef gravy on the turkey and on the side. Called the restaurant and they insisted it "was just darker than usual". They were rude . I know beef gravy when I see it and taste it. It is not edible! Have always liked the restaurant but I am done ! Never again ! read more

The Greek food is legit and it's delicious! I can't stop eating. This food is so good you'll make a mess in your pants. Takeout is what I got I could only imagine how good it is in person. The baklava is really fresh and flaky. I'm in love. read more

Cosmos Restaurant - Baklava - Diners Near Me - Wilmington, Delaware

Stopped by this family diner on the way to Virginia Beach. Very casual, laid back atmosphere. Our waitress, Cindy, was awesome! Very personable and she did a nice job My meal was great. I ordered the Greek Spaghetti. Was cooked with garlic, butter and feta cheese and topped with grilled chicken. Delicious! I could only eat half of it because I was so full. Had the rest later for dinner. It warmed up nicely and there was enough left for my botfly and I to both have a large bowl of it. My entree came with a Greek Salad. That was terrific. Big chunks of feta and olives, finely chopped red peppered and a little onion. Yum! Also the meal came with fresh baked bread and butter! They bake their bread and desserts on site. My only regret was not having enough room to order one of their delicious desserts! I would definitely recommend stopping at this locally owned restaurant. The menu was extensive and I am sure anyone could kind something they would enjoy to eat! read more

Cosmos Restaurant - Greek Spaghetti with grilled chicken - Diners Near Me - Wilmington, Delaware

Cosmos has been around forever. I've lived in DE for over 35 years, and I tried it out for the first time this past month. It's not in the best area of Wilmington, but I've passed by in dozens of times. With a name like Cosmos, you'd expect it to have plenty of Greek offerings. They do, and they have just about everything else you'd expect for a diner-style restaurant. It takes you some time to navigate through the menu, so take a full look before ordering. There is a kids' menu and reasonably priced platters. My gyro was very good. My son' got a kids' pasta meal. The sauce, which we asked for on the side, had a hint of cinnamon, which was off-putting for my son. Wife's chicken salad was very large and is ideal for sharing. Limited parking next to the restaurant, but a nice sized lot across a small cross street. During Covid, we checked in and returned to our car until a table was ready for us; at which time, they called us to let us know that we were ready to be seated. read more

We went here two days in a row while visiting Wilmington from out of town. The breakfast food was good, although service was slow (they noted they were understaffed, which is normal these days). On the second day we ordered two giant eclairs to go. We tried both on the way home but found that the filling in both had gone so sour they were inedible. It appeared that both had been sitting around a while, so keep that in mind when trying the desserts from their case. read more

Cosmos Restaurant - a pastry in a plastic container - Diners Near Me - Wilmington, Delaware

This is the classic all American (greek) diner you know and love. The staff was kind, and while very busy was able to get our food to us incredibly quickly. I ordered coffee, eggs, bacon and potatoes for my side. The eggs weren't as cheesy as I liked, but the bacon was perfectly crispy and the potato were the whole show of my dish. Stayed apart of the clean plate club here and I'll be back again next time I'm in PA!! read more

Cosmos Restaurant - a man sitting at a table eating breakfast - Diners Near Me - Wilmington, Delaware

Atmosphere: When I arrived for lunch, it was busy, but I still managed to get a table. Sitting in the middle wasn't my first choice, but when it's busy, it's busy. The outside is all cobblestone, while the inside has plenty of booths, tables, and a bar. There wasn't anything too unique, but it's a big space with plenty of seating. Coffee: The coffee was hot and fresh, and the whipped cream was homemade! I haven't had homemade whipped cream in a while, so it was a pleasant and exciting treat. Food: I wasn't sure what I wanted to order but settled on the Greek Plate Appetizer and a breakfast sandwich. The Greek Plate was good and came with Grilled Pita, Kalamata Olives, Cucumbers, Tomatoes, & Feta Cheese. It was served with fresh Tzatziki Sauce. I was relatively disappointed with the breakfast BLT sandwich. While it was good, I hoped for more. Maybe a side? It just seemed boring with just the sandwich. It was a good sandwich but nothing too exciting. Service: Our waitress was friendly, and our food came out fast. The issue was when we went to get the check; it took a long time. I needed to hit the road, but it took a while. In all, it was good service minus when I needed to leave. Overall Thoughts/Would I Come Back? I liked Cosmos, and it's a good stop for anyone passing through Wilmington or local. I would go back. I would probably order a lunch item next time. read more

Cosmos Restaurant - French Toast Breakfast - Diners Near Me - Wilmington, Delaware

Cosmo's is alright. A pretty standard diner. Breakfast all day. Some good Greek dishes. I will say, their cakes and desserts all look amazing and everything I've tried has delivered on that. Kids menu has some unique choices. They have a cocktail menu of sorts but I've never ordered any alcohol here. read more

This place is not as good as it once was. I take my elderly Mom there after Mass on Sunday every few weeks when I am visiting. The breakfast food used to he very good but since Spring of 2023 we have gotten somewhat bad food and it has come out cold after waiting 30 minutes for food to arrive after ordering. The waitresses are all very good however. The kitchen needs to get better. I don't plan to go back for a while. read more

This could of been better. 1. I ordered an plain omelette and bacon. Not a bacon omelette with egg. 2. I don't want the meat cooked in my omelette. 3. Home fries slices of potato barely cooked. read more

After a fun filled Saturday night. We all wanted to sit and eat a good meal to discuss all the shenanigans that happened the night before. Cosmos was perfect!! We were sat at a nice size table and instantly we knew we hit the jackpot when Cindy arrived at our table. Her presence was very friendly, inviting and her energy was A++. Cindy was absolutely amazing!!!!!! The food was very refreshing to say the least. I didn't know what to expect as diners can be hit or miss. We all had breakfast food and everyone was beyond satisfied with their meal. I had the cream chipped beef which was a meal I had a few times growing up and I must say it did not disappoint. This will definitely be a gem we will keep on our radar for the future. read more

Great little diner! Looks recently remodeled . Staff was really good . food was good.. we oredered a greek specialty dinner.. very tasteful.

What can I say about Cosmos? I have been travelling to Maryland Avenue in Wilmington for 30 Years and I have most always stopped at Cosmos. In particular I love their Leg of Lamb with Greek Style Roasted Potatoes. I always start with the homemade Vegetable Soup. The Lamb is always great with the Lamb brown gravy. Make sure you call them in advance to see if they have the Leg of Lamb. I think they serve it every other Sunday. My philosophy on Greek Diners is that you should order off the Specials of the Day menu. You will not go wrong. Just don't forget; Cosmos is a Diner. The 5 star review is strictly for the food not the atmosphere. read more

Food was wack ! Wife's Breakfast looked good . I had the gyro best choice for me had to return it . It was embarrassing

You can't go wrong with this all time classic restaurant. The food quality is always top notch and the service is superb. Thumbs up to the owners for keeping up for that long with consistency and a clean restaurant with massive portions. I would visit more frequent if I lived closer but they will have my support anytime I'm in the area. read more

Cosmos Restaurant - Souvlaki done right!!! - Diners Near Me - Wilmington, Delaware

Good food especially for breakfast. The poached eggs are done exactly right. Coffee's good, bacon...all the extras. The extra special part of Cosmos is the waitstaff. A nice group of people. There's another restaurant close by Cosmos who could really benefit from emulating the waitstaff here. The other place hires old hags who hate everyone. Start your day with pleasant people. Go to Cosmos and have a terrific breakfast. You won't be sorry. read more

I just had the BEST salad EVER! The Crispty goat cheese salad, I added shrimp and had them mix in the blush vinagrette dressing. I got it to-go and they actually put the fried cheese and shrimp on the side so it did not make it soggy before I sat down to eat. IF you are trying to eat better I highly recommend trying this salad. I only wish this place was closer to my work. read more

Ordered food from this restaurant thinking it was similar to restaurant I was used to from back home (I'm from out of state). I was absolutely appalled at how terrible the food was. I honestly think you could buy a gyros kit in the grocery store and make a better gyros. The gyros had exactly 4 pieces of meat on it and the tomatoes were rotten!!!!! The salad was old and wilted. The greek salad had 3 olives I small chunk of feta and just plain wilted cheap.iceburg lettuce. Please do yourself a favor and never go to this restaurant! read more

For dinner I DO NOT recommend them.. My husband and I took a bite of our meal and said we didn't like it .. My ham looked gray In spots and tasteless and so husband's meal tasteless.. We usually have breakfast there and it's yummy so I was confused.. I just asked for a refund so we could go home and was told I couldn't have one because it had already been placed in the computer.. (WHAT DOES THAT MEAN) The manager told us no refund but to come back at another time and she would remember us and give us a free meal.. We don't want to cause a scene because they are hard workers so we left. I can only recommend breakfast and that's it .. read more

We have had some good meals here. Not today. We invited our son and grandson to join us for a combined birthday/ Mother's Day celebration. The place was busy, but not crazy busy. We ordered breakfast and lunch. To a person, each one of us was disappointed. When our waitress came back to check on us, even she gave my spanakopita the fish-eye, but didn't offer to send it back due to the overcooking. And how do you ruin pancakes? None of us wanted to cause a scene and ruin an otherwise pleasant day. We travelled here from near Oxford, Pa., so, coupled with the high gas prices, a very disappointing outing! Also, a long wait time before our order was even taken. And please don't sit a party of 4 in a 2-person booth. read more

First time eating here, had breakfast. Ordered the "big breakfast", sort of a sampling of breakfast items. Portions were hardy, food was good. Service was good and responsive. Worth the trip read more

They have a fairly decent menu. I've eaten her several times for lunch and can't say I've had a bad experience. My only issues have been sometimes you don't know exactly what you'll end up with I've ordered the veal cutlet twice with marinara sauce and both times got chicken. Service is friendly and fast so if you're looking for a quick bite with a lot of options this is a place to try out. read more

A diner, yet lots of food choices, with greek dishes also. Food leans towards homemade, mom style. Casual atmosphere. Prices a little in high side but if the resturant was fancier, ie white tablecloths, dim lighting, etc they wouldn't be considered high. Have had greek lasagna, chicken and dumplings, soups, rice pudding, and meat loaf. read more
