Otilia's Mexican Restaurant's (7710 Long Point, 713-681-7203) cream of poblano soup ($5.50) with a michelada ($3.75) may well be the perfect lunch combination. The soup, which is the color of a good guacamole, is velvety-smooth and a little tangy, with bits of tortilla strips adding texture. The michelada is a spicy combination of lime juice, tomato juice, hot sauce and your favorite Mexican beer, and it's served in a salt-rimmed frozen mug. According to one Web site (www.habagallo.com), the drinkwas concocted in Mexico City in the 1940s. Bursting with flavor as soon as it hits your tongue, the michelada tastes like carbonated hot sauce -- most unusual, and most delightful.
