Best Californian Restaurants in Pasadena

I’ve been seeing Osa Rooftop pop up on social media since it opened, and it’s always caught my attention while driving along Colorado Boulevard, especially with its old-fashioned films projected onto the wall. Friday night was a little busy, as expected, but our reservation was honored promptly with no wait. We were seated outdoors with a beautiful view of the San Gabriel Mountains, which were partially hidden in the evening clouds. The staff was attentive and friendly from the moment we arrived, checking in throughout our drinks and dinner without making us feel rushed. The cocktails were fantastic! I ordered the Sweet Relief, a vodka, grapefruit, and rosemary combination that was excellent. The Negroni and martini were equally well executed. Dinner was where Osa really shined. The steak frites was a classic and delivered as expected, but the standout was the al pastor chicken with Napa cabbage salad. Absolutely incredible! To top off the evening, Osa was projecting the original black-and-white Dracula, which was a perfect touch for Halloween weekend. Between the atmosphere, excellent cocktails, delicious food, and attentive service, Osa made for a wonderful Friday evening. Definitely looking forward to returning!

Incredible!! 20+ years of excellence! Everything incredible! Love supporting locally owned & operated. Every time I come here- I feel well-taken care of. Great authentic Italian food, amazing ambience, & the owner is always attentive. One of the best places to dine in all of LA County. 💖

It was our first time trying it and it was AMAZING! We went for an earlier dinner but it was becoming more packed as we left.

We enjoyed the fabulous happy hour with pineapple margaritas followed by wine and one of the best pumpkin pie slices we ever had. The pie is a true creation of Chef Ian Gresik!

Loved the food and atmosphere! Very quiet on a summer Sunday night. The prices have gone up compared to what was listed on the menu. Even though the waiter told us some prices had increased, we were caught off guard a bit by how much (our appetizers were 50% more). Still we were treated to a delicious açai. And all the food was very delicious, so we will be back!
