Cinco de Mayo will soon be upon us, and to celebrate, Tuesdays are "Margarita Martes" nights at the BottleNeck Lounge, with discounted mojitos ($6), Sauza margaritas ($7), Coronas ($3), and nachos ($7; with cheese, tomatoes, olives and salsa). Other days bring other deals: budget wine specials ($15 for assorted bottles of South African origin) on Fridays from 4–6 pm, and $10 grilled cheese/bloody mary combos are served all day Sunday (1 pm–10 pm). Finally, Chihuahua owners whose pets are cursed with wildly bulging eyes, sweat-ringed armpits, or midsections that have grown unsettlingly large will delight in BottleNeck's upcoming Ugliest Chihuahua in Seattle contest (register your dog's photo at www.bottlenecklounge.com, winner announced May 5).
