Las Velas is a consistent favorite for work happy hours. It's never excessively crowded, and is conveniently located right in market square. The margaritas are enormous (and rather potent). Service is very speedy, and the food is always up to par. By far the best deal is the appetizer trio though. The best chips, along with a good sized bowl of guacamole, queso, and salsa. Definitely a must for a happy hour! Give this place a try!
