The bar located just off the lobby at the Four Seasons Hotel is a throwback to an earlier era, when love-struck couples donned their best duds for a night on the town. Spare in its details -- cushy chairs, a few framed artworks and lamp-lit tables that emit a hazy orange glow -- the room springs to life every evening as a jazz pianist plays standards from the corner. There are no televisions, no fluorescent beer signs, no patrons staring dumbly into the bottoms of their martini glasses. The joint has class. The bartenders are efficient, gracious and knowing, serving up tips on how to score Astros tickets at playoff time along with complimentary bowls of wasabi peas, cashews and almonds. Though the hotel sits in a prime spot adjacent to the ballpark, convention center and several concert venues, it's easy to while away an entire evening without ever leaving.
