Be The First to Experience New Western Bars, Rooftop Lounges and LGBT Cocktail Clubs. Costa Mesa is earning itself the title of Orange County’s hottest and trendiest city. It’s the perfect mesh of hipster and hip, where foodies flock and where independent businesses thrive. When we thought Costa Mesa couldn’t get any cooler, it opened up eight new restaurants under our noses. From OC’s only spot with a mechanical bull to rooftop bars and sunlit cafes, these new restaurants are not to be missed. Not only is the Westside getting a new cocktail club, but The CAMP is coming back to life with two new Costa Mesa restaurants to try. Mark your calendars for opening dates and buckle up because this is going to be downright delicious. Here’s everything we know about what’s new and coming soon to Costa Mesa.
