Happy hours (and reverse happy hours after about 10:00 p.m.) are one of Vegas’s best kept secrets. Belly up to the bar of gourmet restaurants like Aria’s American Fish for excellent deals on drinks and bites such as lobster rolls and mac ‘n’ cheese. Hit up Red Square Bar at Mandalay Bay for drinks specials and a taste of caviar, or visit nearby Stripsteak. Try the cocktails at the Cosmopolitan's Comme Ça, or head to Fashion Show mall and check out RA Sushi or El Segundo Sol. If you're inside the Forum Shops in Caesars, both Trevi and Sushi Roku have happy hour specials to put a smile on your face.
