Drinking in Vegas can have all the sophistication of southern martini lounges. Blue Martini, located in the mega retail development Town Square, is roughly twice the size of its sister bars in Florida, spanning 15,000-square-feet and encompassing four bars and an outdoor patio. Still, in spite of its size, this drinking den is packed on a regular basis, thanks, at least in part, to its happy hour: Drinks and food are half-priced, daily from 4-8pm. Arrive early-or reserve a table-in order to land a seat and opt for the mango Martini, by far the bar’s best-seller.
