I had stopped going to Shake Shack because they took the spicy chicken sandwich off the menu. We got some free burger coupons and decided to get some burgers. The burgers were decent with the exception they NEVER follow through with toast both sides of the buns. The major complaint I have are the fries. They are just not good. I'm not sure what the solution is but those fries gotta go. The Passion lemonade was good. So unless they bring the spicy chicken sandwich back...

I am a big fan of In and Out, this is my first visit to Shake Shack. It’s absolutely on par with In and Out. Both are fresh and taste great. I’d recommend this place anytime. It’s a must taste burger if your into hamburgers and fries. Awesome. Forgot to mention! The huge outside patio area is Fog friendly! Bring your pup with you. They will love the food here too!

Parking: Excellent parking. Huge lot.

Kid-friendliness: Plenty of...

Huge shoutout to Corey, the manager, for a great lunch experience! I stopped by for a quick bite during my break, pressed for time, and not only did I get my order incredibly fast, but it was fresh and delicious. The whole team was amazing, and his kindness totally made my day! Amazing food and an even more amazing staff!
