    The Desperado burger, bowl style, was a big, deleicious, and mostly healthy meal. It was a little hard to hear the ticket numbers and one of our party members got their food much later, which suggested there wad a communication problem. But the food was enjoyable and it was worth the visit.

    This evening we came from Cayucos as I was encouraged from a family friend while we are on vacation to get a free burger for my birthday. We got here and we were met by Haley at rhe cash register, she was super friendly and encouraged us to join the VIP Club so we can all get free burgers. Hailey handed us a menu, gave us a big welcoming smile and answered our questions. Hailey told us about the specials and to check our emails for monthly specials. I highly recommend this burger joint. It was delicious!

    It's just an average frozen bland burger with a high price point. The buttery toasted bread was the highlight. Produce was very fresh. I guess we are burger snobs, lol. Staff were upbeat and friendly. Patio needs a good de-webbing and pest service.

    We have been here several times and the food and service is consistently good. The garlic fries have a little too much garlic on them IMO. The deep fried mushrooms are delicious, but they were out of them the last time we went. They have outdoor seating which is nice since we take our dog with us a lot of the time.

    The girl who took our order was so fantastic, extremely personable and very friendly. She seemed to be really engaged with most of the patrons there. I think someone mentioned her name was Hailey. The food was great, but her service really made the experience great! Go see Hailey.

    Sylvester’s in Los Osos is my favorite Burger/Hot Dog spot. The crew is always so nice and I watch them really help out seniors and it’s nice to see them take care of the community. The Sly Street Dog is the best tasting Hot Dog I have ever eaten. The Garlic Fries are a must have. And both the black and bleu burger and the buffalo bleu burger (the ladder is made with buffalo meat) are top notch burgers that I honestly think could win some competitions. I love Sylvester’s and if you’re reading this review, I strongly urge you to go.

    Decent place to get some burgers. They have 3 locations and we visited the Los Osos place. The burgers are pricey but they taste good. We also got some free fries on Friday. The place was not busy at all. Lots of indoor and outdoor seating. Check it out of you are in town.
