Traveling to San Diego and am interested in trying one of those places. Did a little research but trying to figure out what I should be looking to pay at those places?
Also, how far is it to TJ from the GAs Light district in San Diego?

Any help would be greatly appreciated.

Fees and services are negotiable, but expect to pay around $60.00 for a 30 minute session.  Negotiate the price and everything you want—dfk, bbbj, etc.—in advance.  You’ll also pay for the room ($10-15) and at least one round of drinks.  (You’ll pay around double for a chica’s drink.)  Don’t forget to tip the towel boy.

Gaslamp is about 15 miles from the border, a 30-minute drive when traffic isn’t heavy.  You can also reach the border by taking the blue line of the trolley.  From the border to Adelitas or Chicago Club is $5.00 using a yellow cab.  (They’re about a block apart; the Zona is confined to a few blocks.)
