When you sink to the level of tequila shots, you generally think college bar or Tex-Mex dive. Too bad. Agave Azul is indistinct enough, sitting on one corner of a lonely shopping strip, and they serve Tex-Mex fare, but the place is designed for more sophisticated hard-core alcoholics. They separate the bar side from the dining room with a wall of windows so, while you chug agave juice, you can stare at those sorry-ass practitioners of sobriety. They stock, by our count, about 80 different bottles priced by the amount of time the spirit sat in barrels--$8 for reposados, $9 for the older anejos. On the top shelf there's a set of premium tequilas, such as Don Julio Real, which will set you back 30 to 50 bucks a shot. That's a lot to choose from, but don't worry. Agave Azul offers flights of regular tequilas and a sampler of the ultra high-end stuff.
