The bar is packed and the staff is struggling to keep up, though still smiling. Groups of party people at high pub tables are tasting each other’s craft brews. Tattooed girls and guys with shaved heads are playing a loud game of shuffleboard in the corner. That’s just the activity in the bar ... there’s also a huge second-floor patio and another bigger, boisterous dining room where patrons are throwing down ahi tuna tacos and bacon-cheddar tater tots. Where are we? Believe it or not, this is Downtown Summerlin. The 14,000-square-foot Public School 702 is the latest franchise to find a home in the still-growing mega-complex, but it doesn’t feel like a chain bar and restaurant. It feels like going back to your favorite college bar for a meetup, only the beer is better (19 taps and an impressive list of bottles and cans). It’s no nightclub. PS702 is super-casual, per the rules of going out in Summerlin, but there’s a lot more energy. It’s even a little unruly, which is a refreshing change of pace.
