Cosmos Burger

I truly enjoyed my visit here. I've been looking for a great burger experience since my favorite one in Carlsbad closed years ago. Nephew took me here and told me to try it out and it did not disappoint. Came in at a perfect timing as it wasn't crowded in the afternoon. I enjoyed my meal and the Burger is just tender juicy good. Reasonable price and something I will definitely go back for. It was very neat inside and the colorful design of the store is just vibrant and inviting. Great service as well. The crew offered many in the menu that she thought I might like. Thank you for existing 😅😉😊😊

For my taste, this is the best burger in Oceanside. I mentioned this to the counter person once, and he pointed to a certificate hanging on the wall indicating that they apparently received an award for...best burger in San Diego. I love the juicy, flavorful, beefy smashburgers at Cosmos. So far I've had the Cosmos Burger, BBQ Burger, the Blue Cheese Burger, and the Spicy Jam Burger (my favorite)--and loved them all. Absolutely delicious. Great sauces and ingredients (like microgreens) that bring a delightful balance of flavors. I've brought friends with me several times, building Cosmos up as the best burger in town, and though skeptical coming in none argued with me afterwards. They tend to also appreciate that Handel's ice-cream is just a few doors down for after. I've also enjoyed th

The shop is cute. We ordered lavender lemonade, cosmo burger and spicy chicken sandwich (not spicy at all 😅). Tastes are good, I like their sauces for burgers.

Everything was excellent! My husband got the spicy jam burger, I got the truffle burger, and we shared the monkey fries. Highly recommend all 3! The food was delicious, burgers were super juicy and flavorful, and the fries were unique and so good! Everything was fresh, cooked perfectly, and presented nicely. The staff was very welcoming and attentive, and our food came out quickly. We're looking forward to coming back!

This place was pretty pricey (and crowded on a Friday night with little seating), but had some good food and fast service. The spicy jam burger was pretty good. It was a unique style that I hadn't seen before, so definitely worth a try. It was a bit sweet and kinda underwhelming for my taste, but still enjoyable. Fried cauliflower and the fries+onion rings were a good addition. The burger filled me up, but it's always nice to have some sides, which have to be ordered additionally. They also serve draft beer, which is a plus.
