Dos Caminos has closed for the second time in Las Vegas. The upscale Mexican restaurant opened in Summerlin this spring after a renovation on the West Charleston space that formerly housed Agave, but it could only hang on for a few months. A brief statement from a restaurant spokesperson indicated "the current location was not suitable for the brand," and that BR Guest hospitality company "will continue to search for the ideal location for Dos Caminos in Las Vegas." The restaurant originally opened at Palazzo and closed the first time in 2011.

Culinary Dropout at the Hard Rock Hotel is keeping it casual with new happy hour specials available Monday through Friday from 3 to 6 p.m. Six-dollar plates include grilled cheese sliders with tomato and bacon, a rotating chopped salad or (our favorite) soft pretzels with provolone fondue. Too rich for your blood? The house-made potato chips and onion dip are just $3. Mug beers are also $3, well drinks are $4 and the Double Blind special—a paper bag beer and a shot of the bartender's choice—is $8.

Looking for more cheap grub? Rockhouse at Venetian/Palazzo—it's kind of in between the two resorts—has kicked off Taco Tuesdays, featuring $1.50 tacos all day long, a perfect match for the dive bar's $7 margaritas or $5 tequila shots.
