    Wine night
    Jan J.

    Came here for a special anniversary dinner. We had called and pre booked my wife's favorite - lamb shank - so tender so delicious. Item is not on the menu but with notice they are willing to do special requests. I had the pork chop which was amazing also. We brought our own wine but their selection is very nice. They do wine tasting once a month on Tuesdays which I will book soon.

    Cosmo's Bistro is an authentic Italian restaurant located in Glendora. The restaurant has cozy and relaxing vibes. There is a delightful patio outside. I wanted to enjoy the patio vibes but it was very cold at night.We preferred to stay inside. Shoutout to Courtney! Courtney was such an amazing hostess. She came promptly to our table with the menu, shared with us the Chef specials of the day, then came with hot, fresh and delicious bread. She also stopped many times at our table to fill our glasses with water and check on us. They have delicious menu including appetizers, entrees,salads, pizzas, pastas, and desserts. We ordered : -Bruschetta tomato, feta and basil 4/5 -French Onion soup 4/5 was rich and flavorful. - Linguine Al Frutti Di Mare 4/5 It had mussels,clam, shrimp, Calamari. It was very flavorful and had generous amount. - Miramonte chef special 3.5 /5 It was the chef special of the day. I felt that it was missing some flavor. - Spoumoni 5/5 Was rich and had the common Spoumoni flavors; pistachio, chocolate, and cherry. Overall, the service was great, the amount was generous, and the price was reasonable.

    So I just recently tried cosmos for dinner and my wife and I really enjoyed it, I had the seafood linguini and it was perfect , wife had chicken Marsala and she loved it , salads were fresh , bread was crunchy and soft at the same time, stuffed mushrooms ridiculously good , finished with the best tiramisu I've ever had 3 nights later ... short rib ravioli with Marsala sauce was unreal , daughter had shrimp fettuccine Alfredo , she loved it , finished with two delicious cannolis , service from Hugo was great , the chef cosmos was friendly and this guy knows how to cook great Italian food , literally can't wait to go back Thanks cosmos for getting it right

    This smaller place has a really pretty and nice patio area. What a nice and large selection of foods! I was disappointed they didn't have the prosciutto and fig pizza that I really wanted to try. Instead I got their grilled salmon salad which was plentiful and the vinaigrette dressing made it so tasty. Our group shared the baked Brie appetizer which was so delicious and delightful! I was surprised because I'm not a Brie fan. Others had some nice and fancy pasta dishes plus the pizza is big and very well made. Service was a bit slower but our group had plenty of fun talking and eating the excellent bread perfectly baked with olive oil and balsamic vinegar. Yum!!

    Lobster stuffed mushroom sooooo yummy

    First time here! Everything was absolutely wonderful! Courtney our Server was awesome the food OUTSTANDING! We will definitely be back!!!!

    I had my baby shower here and it was great. Cosmo helped us with the menu to accommodate our guests. The staff was extremely attentive . We were able to go in before opening to set up which was so nice. The price was great as well. I would definitely recommend for parties !

    First things first The bread especially the focaccia they give our before your meal is amazing So fluffy and perfect flavor The service is really good they make you feel like family The ambience is quiet and perfect for a family dinner or date night The food is also well made and you can tell it's made to order. I loved that we ended up here last minute on a Friday night and the wait wasn't extremely long. I recommend to anyone looking to switch up your dinner date night

    A Hidden Gem for Italian Food Lovers! It all started with a simple plan to eat somewhere close to home, and I decided to give Cosmo's Bistro a shot. Little did I know, I would absolutely fall in love with this place! For anyone planning to try this restaurant for the first time, start with their stuffed mushrooms! Seriously, they are the best stuffed mushrooms I've ever had. You also can't go wrong with their fresh, flavorful salad--it's a perfect start to the meal. (Excuse the photo in this review--everything was so good, it was devoured before I could snap a proper picture! ) Be sure to ask about the chef specials, especially their Miramonte! If you're a fan of seafood and creamy sauces, this dish is an absolute must-try. Their sausage pizza is another standout--so flavorful and perfectly baked. Although I haven't had the chance to try their paella yet, I've already ordered it for New Year's Eve, and I can't wait! Judging by everything else, I'm sure it'll be fantastic too. If you're someone who loves dining at Spaghetti Eddie, do yourself a favor and try Cosmo's Bistro. You won't be disappointed! The service here is incredible, making the entire experience even better. This place has definitely earned a spot on my favorites list. Highly recommended!

    Came in on a Saturday night to catch up with friends . It was a chilly rainy evening and made for a relaxed and enjoyable time. They had a guitarist playing Beatles songs which adds to the ambiance. Shared a baked brie appetizer and went nicely with a glass of Pinot grigio. The entree sizes are perfect for sharing or taking some to-go. The pesto chicken was tasty and light . The staff was friendly and attentive.

I tried the jalapeño bagel with cream cheese and it was immaculate. The cream cheese ratio was perfect (not skimpy, not overloaded), and the bagel was toasted exactly how it should be - nicely crisped but not hard to chew, and definitely not soft or soggy either. I also got the Firebird sandwich, and WOW. As a savory girl, this one really hit the spot. The amount of buffalo sauce, pickles, and Dijon mustard was perfect - flavorful and bold without being overbearing. The portion size was great too. It was filling, I could easily save half for later. For drinks, I ordered their seasonal iced cherry pie latte, and I'm honestly still thinking about it. I usually don't go for sweetened coffee drinks, but my oh my... this was genuinely one of the best lattes I've ever had. Balanced, smooth, and not overly sweet. I also tried the seasonal Love Machine matcha, and it was amazing. The matcha tasted high quality -- not bitter and not grassy at all - with the perfect amount of sweetness. On top of all that, the service was immaculate, and the music/vibe inside was so good. Definitely one of those places you want to keep coming back to.

The staff is friendly, welcoming, and always creating a great vibe the moment you walk in. The drink selection is top tier, whether you're in the mood for coffee or something a little different. And if you hang out long enough, you can even grab a beer from a local brewery, which is a nice bonus I haven't tried much of the food yet, but the menu looks solid with plenty of good options. The atmosphere has a classic Americana with an alternative feel, with good music always playing in the background. They also have a car meet-up on the weekends, check out their IG page Overall, it's a great spot to hang out, work, or just catch up with someone.

Based off the reviews and photos that I saw on Yelp, I decided to get the 'West Coast Cheesesteak' in a large to share between two people. They let you choose what cheese you want and the reviews said that the cheddar cheese sauce was amazing. Honestly, I wish I stuck with what I like and got the provolone. The cheddar cheese sauce wasn't my cup of tea but the two people that I shared it with said it was really good. I did also wish that the bread was more toasted and the entire cheesesteak had more texture to it. The bell peppers added a nice spice to each bite and was honestly my favorite thing about the sandwich. It was also $20 for one cheesesteak.

    So Fresh & Delicious!…read more I tried C&R Fresh Foods for the first time a week ago. I did some research on Yelp to see the menu and recommended options. I was craving a wrap so why not come give em a try. The parking lot has plenty of spaces as it located on the long strip mall in this part of West Covina. The location is pretty chill and quiet outside of the TV playing soccer. The staff who took my order was friendly and allowed me to try sample some smoothies. I came there for the BLT wrap with avocado. My order was served within a few minutes. The staff offered jalapeños on the side as well and constantly checked in with me. I was happy with this wrap! The freshness of the veggies and the crunch from the bacon was perfect. One specific detail I'd have to mention was the cream cheese they use in the wrap. It elevated that wrap it to a new level and brought out all the flavors. I'd return again just for this item. Good customer overall with great food. Come by and try out C & R Fresh Foods! ( ^_^)b

This one was also surprisingly delicious and a bit unique as it had a slight nutty flavor to it. I think the drinks here are made better than Jamba Juice or Robeks.
