For the Priority Pass Lounges: the Avianca lounge is self serve, but nothing to write home about (and close to the AA gates) (liquor is ok, food options are a soup, pasta and some meat item, flan is good though). The other 2 Lounges (Grand Lounge and Lounge 19) do not have self serve bars, and have a slightly long walk to the AA gates. For Grand Lounge and Lounge 19, you will be attended to by a server, who will serve you drinks, and you can get 1 entrée item for food, as well as sandwiches, chips, salad, etc.
